Drafting Currently, it is necessary for designers to create paper drawings and layouts of their parts and assemblies. This course will cover the steps necessary to create multiple view drawings and detail sheets of parts and assemblies. This will include all annotations and dimensions that are necessary to finish a completed drawing. The drafting workbench includes a variety of icons that allow for the creation of these drawings. It is normally considered that the workflow should be from 3D to 2D. There are some tools for generating 2D geometry independent of a 3D model but it is not a common occurrence in most cases. You should already have a good understanding of Part Design upon starting this course. This will complete a basic cycle of events from designing your own parts and creating a multiple view drawing. The course will also show how you can create a multiple sheet drawing of an assembly as well as the detail drawings of the individual parts. Unfortunately the industry still requires and depends heavily on paper drawings. There has been much discussion on “paper-less” environments where the end users would just pull up the design on the computer and analyze the areas of interest. In the future that may be the case but until then this is an extremely important aspect of your V5 knowledge. At any point it will be necessary to create drawings for technical publications and handbooks. This class will also explore the options available to export pictures from CATIA to wordprocessors that then could be used to create technical documents or even web documents.

Drawing Screen

This is how the drawing screen looks with two sheets and one empty view. Normally when starting a new drawing you will only have one sheet and no views. Notice that this screen looks a little different than the Part Design screen. A

Each sheet created in a drawing is represented in the specification tree. It is possible to create many different sizes of sheets.

B

Each view created in a drawing is represented in the specification tree under the sheet the view belongs to.

C

The current sheet is shown in each drawing. The different sheets are represented along the top with tabs and you can change the current sheet by selecting the appropriate tab.

D

Each view created has a view axis that represents the orientation of the current view. It is possible to hide or show the view axis.

Drafting Basics Starting a New Drawing This will cover the necessary steps to create and modify a CATIA Drawing. There are a couple different ways to start a CATIA Drawing. The first way is to start a model the same way that you created a document in other classes, with pull down menu File or using the equivalent icon in the bottom toolbar. Another way is to be in a document such as a part or assembly and then change to the Drafting workbench. The first method will be discussed now. This is useful if you want to just start a new drawing and begin modeling in 2D. Select the new icon in the bottom toolbar. This allows you to create a new document. The document that is created depends on the selection you make: either an analysis, drawing, part, or product.

Select Drawing. This will allow you to create a new type of document called a CATDrawing.

CATIA® V5R14

Select OK. This will open the New Drawing window. This is used to determine the drawing’s standard, sheet style and orientation.

Standard

You have several standards to choose from the most common ones being ASME, ANSI, ISO and JIS.

Sheet Style

Defines the size of the sheet, in terms of ASME you have A through F sizes along with Letter and Legal. The Width and Height will be specified in the corresponding locations. In addition to those options you have a J U.S. Standard.

Orientation

Defines the orientation, whether it is Portrait or Landscape.

Set the Standard to be ASME, Sheet Style to be A ANSI and the orientation to be Landscape. Select OK. The new drawing is started and formatted according to the settings you specified in the New Drawing window.

Drafting Basics, Page 18

CATIA® V5R14

When you first start a new drawing, it contains only one sheet, called Sheet.1. The sheet is formatted to the setting determined for the whole drawing. Later you will use multiple sheets, but for now you will use only one. You can set some properties for each sheet, such as, the name of the sheet, the scale for the sheet, the format of the sheet and the projection method to be used when creating views. You can also specify how the views will be positioned and define a print area. Using the third mouse button select on Sheet.1 and select Properties. The Properties window appears.

Drafting Basics, Page 19

CATIA Drafting

CATIA® V5R14

Change the name to be Drafting Sheet 1 but do not press Enter. The name has been changed to Drafting Sheet 1. You can also change the scale and the format of the sheet here if you want, but you cannot change the standard of the sheet. You can change the Projection Method, which determines if it should use first angle or third angle projection when creating views. The Generative views positioning mode changes where the axis of the drawing will be. Print Area deals with exact area of the drawing that you wish to print. Select OK. This closes the Properties window and returns you to the drawing. Sometimes more than one sheet is needed to contain the entire drawing. CATIA V5 allows you to add sheets to the drawing and also delete them. Select the new sheet icon. A new sheet is created and added to your drawing. The sheet is the same size as the first sheet. You can switch between the two sheets using the tabs at the top of the drawing or by double selecting on the sheet name in the specification tree.

The new sheet uses the same scale as the first sheet. You will now delete the sheet you just created. Select Sheet.2 from the specification tree and press the Delete key on the keyboard. A Confirm Sheet Delete window appears. This lets you know that the deletion cannot be undone. Select OK. The sheet is deleted. Close this document. You will now create a new drawing using an alternate method.

Open the Pawl Hook document. Notice that this is a part that has already been created. You will now enter the Drafting workbench. Change to the Drafting workbench. You can change workbenches by using the pull down menu Start or by using the change workbench icon. A New Drawing Creation window appears.

Notice that the standard, format, orientation and scale are all set to what you used last time. You can change those settings by using the Modify button and this will open the New Drawing window that you saw earlier. You now have the option of choosing an empty sheet, similar to what you did when you created a new drawing earlier, or you can choose one of the automatic layouts. The four options are empty sheet; all views; front, bottom and right; or front, top and left. Choose the empty sheet option and select OK. This will create a drawing just like before with one sheet that is empty. For purposes of understanding the other three layouts, pictures are shown below with the result of each one. This is the all views option. Notice that all the views are generated and appear in the drawing, but they do not fit on the sheet. You will learn more about views later in this course.

Creating Views from a Part There are many types of views that can be created in CATIA Drafting. This section is designed to cover all of the various types of views that can be created. As discussed earlier you can create a drawing in one of two ways, you can either begin a drawing with an empty sheet or with a configuration of views. Initially you will be starting a new drawing with an empty sheet. Before you begin, make sure that you do not have any other windows open in CATIA. Open the Views document. You should notice that this is a part. You will be creating views for this part. Start a new drawing with an empty sheet, the settings should be ASME Standard, D ANSI Sheet Style and Landscape orientation. You do not want any views in the initial drawing. You can always assume ASME Standard and Landscape orientation for all exercises unless otherwise specified. Change your window configuration to be Tile Horizontally. You can do this by using the pull down menu Window, Tile Horizontally. It should appear similar to the diagram shown below.

CATIA® V5R14

Front View The first view created is normally the front view. You can create a front view by defining the 3D object that you want to use and defining the plane that should be used to define the view. Select the front view icon. and create the front view.

This will allow you to define a plane from a 3D object

Select the plane shown below from the part. This will define the plane that you want to use for the front view.

The diagram shown below should appear in your drawing window.

Notice that the part appears in the drawing window and you have a blue orientation circle in the upper right-hand corner of your window. This circle allows you to orient your view before actually creating it. Once the view is oriented the way you want it then you can either select on the center dot or select outside the blue circle to create the view. You are going to investigate the various options that you have available for orienting the view.

Orientation Circle

You can select on the right or left arrows to rotate your part inside the view to give you a different plane in which to create your front view. The same goes for the up and down arrows but it rotates your part in the other direction. This will rotate the part 90 degrees with each selection. The two curved arrows will rotate your part within this plane either clockwise or counterclockwise. The amount that it rotates defaults to 30 degrees but you can edit the angle. You can also use the green knob to rotate your part around by selecting it and dragging it around the circle, it defaults at 30 degrees but it can be edited as well. Select the right arrow until you turn it all the way around back to the original orientation. You should have to select the right arrow four times. The diagrams below show what your part should look like after each selection.

Select the up arrow until you turn it all the way around back to the original orientation. You should have to select the up arrow four times. The diagrams below show what your part should look like after each selection.

CATIA® V5R14

Select the right curved arrow three times. You should notice the green knob now turning around the circle as well as the part turning. The diagrams below show what your part should look like after each selection.

Notice that it rotated the part 30 degrees each time. You can modify that by selecting the third mouse button while on the curved arrow and choose the Edit Angle option. Using the third mouse button select on the right curved arrow and choose the Edit Angle option. The Angle window should appear.

Change the Rotating angle to 45 degrees and select OK. Now when you select on the curved arrows they will rotate the part 45 degrees instead of 30 degrees. Select the left curved arrow two times. This should turn your part back to its original orientation. You can also use the green knob to rotate your part. All you have to do is select the green knob and while holding the button down, drag it around the circle. This also defaults to 30 degree increments. You can change the settings for how the green knob works by using the third mouse button. You have to be very careful when trying to select the green knob because if you select off of it and outside the blue circle the view will be created automatically. You are now going to change the angle of your part to be at 90 degrees.

Projection View This view is created by using an existing view, usually the front view, and then selecting a position for the view. The view that gets created depends on where you select. If you select to the left of the view then you get the left view. Projection views are created orthogonally to the active view. Select the projection view icon. It is located under the front view icon. You can now position the cursor and select the view that you want to create. Position the cursor to the left of the front view and select. You should have seen a preview of the part before you selected. Your drawing should appear similar to the diagram shown below.

A closer look at the view is shown below.

Your drawing

A closer look at the view is shown below.

You can move the views around within the sheet. The default setting is for the views to align with each other. Therefore you can only move the left view right and left and you can only move the top view up or down. You move the view by selecting on the frame of the view with the first mouse button and while holding the button down, drag the view with the mouse. If you move the front view around, all the other views will move with it. You will learn how to make the views not align later in this course.

Isometric View To create an isometric view you orient your part in Part Design the way you want it and then using the appropriate icon you select the body and the isometric view is generated. Change the configuration of your windows to Tile Horizontally. Select the isometric view icon. It is located under the front view or projection view icon. This will allow you to select the part to create an isometric view. Select the part from the Part window. The preview of the isometric view appears in your drawing. Once again you can use the orientation circle to orient the view in what ever position you like. Select outside the blue circle to create the view. It should appear similar to the diagram shown below. Note: only the view is shown below.

Move the isometric view so that your drawing appears similar to the one shown below.

Advanced Front View The advanced front view option works exactly the same as the front view option except that you can specify additional information during the creation of the view. Examples of the information that can be specified are the view name and view scale. Open the Advanced Front View document. You are going to create a new drawing using the advanced front view option. Start a new drawing with an empty sheet, the settings should be ASME Standard, D ANSI Sheet Style and Landscape orientation. You do not want any views in the initial drawing. You can always assume ASME Standard and Landscape orientation for all exercises unless otherwise specified. Change the configuration of your windows to Tile Horizontally. Select the advanced front view icon. It is located under the front view or isometric view icon. A View Parameters window appears. You can specify the View name and the Scale for the view before you create the actual view.

Change the View name to be Large View and the Scale to be 2.0 and select OK. Select the face shown below.

Local Axis System When you create a view from your part, you have the option to select an axis system that you want to use as the view axis. If you do not select an axis system before selecting the part then it will use the global axis as the view origin. Select the front view icon. define the plane for orientation.

You are going to select an axis system first and then

Select Axis System.1 from the specification tree in the part and then select the same face as before. You will probably have to expand the Axis Systems branch in order to see the actual axis system. Create the view. The view is created similar to the diagram shown below.

Notice that the view axis is in the location of the local axis system from the part instead of using the global axis position. Save your drawing and close all documents.

Unfolded View The unfolded view option is used to create a view of a sheetmetal part created in CATIA. It is defined similar to the front view but it unfolds the view for you onto the drawing. This option only works with parts created using the sheetmetal options available in CATIA. Open the Unfolded View document. You should notice that this is a part with Sheet Metal Parameters. You will be creating an unfolded view of this part. Start a new drawing with an empty sheet, the settings should be ASME Standard, D ANSI Sheet Style, Landscape orientation. You do not want any views in the initial drawing. You can always assume ASME Standard, Landscape orientation for all exercises unless otherwise specified. Change your window configuration to be Tile Horizontally. You can do this by using the pull down menu Window, Tile Horizontally. Select the unfolded view icon. It is located under the front view or advanced front view icon. This will allow you to select a face of the part to create an unfolded view.

Select the face of the part shown above. The preview of the unfolded view appears in your drawing.

Select outside the view to create the view. It should appear similar to the diagram shown below. Note: only the view is shown below.

If the axis lines do not appear in your view, change the Properties of the view to show Axis under Dress Up. Notice that the view shows the sheetmetal part as if it was unfolded. This will give you an accurate view of the actual piece of sheetmetal that would be required to bend into the desired shape. Note: This is very different than creating a front view of this part using the same face. The diagram below shows you what the front view would have looked like.

It is important to remember that this option only works if the part was created with the sheetmetal options. Save your drawing and close all documents.

Extracted View from 3D The extracted view option will create a view extracted from a part that has a view defined. It is defined by selecting a view that was created in other operations. This exercise will show you how to use this option with a view generated for functional dimensioning and tolerancing. Open the Extracted View document. You should notice that this is a part with a Annotation Set that includes a Front View. You will be extracting a view from this FD&T view. Start a new drawing with an empty sheet, the settings should be ASME Standard, D ANSI Sheet Style, Landscape orientation. You do not want any views in the initial drawing. You can always assume ASME Standard, Landscape orientation for all exercises unless otherwise specified. Change your window configuration to be Tile Horizontally. You can do this by using the pull down menu Window, Tile Horizontally. Select the view from 3D icon. It is located under the front view or unfolded view icon. This will allow you to select a FD&T view from the part. Select the FrontView from the specification tree of the part. It should show you a preview of the view in the drawing window. It is important to note that the view created in FD&T should use the same standard as the sheet that is defined. Select outside the view to create the view. It should appear similar to the diagram shown below. Note: only the view is shown below.

It is important to remember that this option only works with parts that have views defined from a previous operation such as functional dimensioning and tolerancing. Save your drawing and close all documents.

Auxiliary View The last projection view that will be covered is the auxiliary view. This is used to create a view that is not orthogonal to an existing view but is looking at a particular side of the part. It is defined by selecting an element that defines a view plane in the current view. Open the Auxiliary View drawing. Make sure you open the CATDrawing and not the CATPart. You should see a drawing that contains a Front view and a Top view.

You are going to create a view looking at the angled side of the Front view as shown above. Select the auxiliary view icon. It is located under the front view or view from 3D icon. This will allow you to select an existing line to define the orientation of the view or you can define a start point and end point to define your own line. Either way it will create a view looking at your part normal to the defined line. Select the line shown above from the Front view. This will define your auxiliary view to look at the slanted portion of the part. You now need to define where you want the auxiliary callout to be positioned.

Section Views and Section Cuts Section views and section cuts are views that show the profile of a part at a position, with the areas that contain material being filled with a pattern. If the part has a material applied to it then the pattern will display based upon that material. The difference between a section view and a section cut is that a section view will show what geometry lies beyond the cut line whereas a section cut will only show what exists at the cut line. The cut line can be either a single line or it may have jogs in it to show a cut through the same part at different places. Also available are aligned section views and aligned section cuts. The aligned style allows there to be cut lines that are not parallel and the resulting view is shown perpendicular to the cut lines. Open the Section Views and Cuts drawing. Make sure you open the CATDrawing and not the CATPart. You should notice that the Front view is active since the outline is red. You are going to want the Top view to be active since you are going to create a section view using the Top view. Double select on the Top view. The frame of the Top view should change to red. Before you define the cut line you will want to open the Section Views and Cuts part. Open the Section Views and Cuts part and Tile Horizontally. You do not have to have this part opened in order to create a section view but it will show you the cut plane in the 3D part as you define the cut line. Select the offset section view icon. top view.

This will allow you to define a cut line in your

You should notice the cut plane appears in the part window as you are defining the cut line. It should appear similar to the diagram shown below.

Double select at the second location. Since this is the end of your cut line you must double select. You can now position your section view. Position the view above the Top view as shown below. You should notice the section arrows appear on your cut line.

Note: You also have the option of selecting circular edges to define the cut lines. If you select on a circle it will automatically use its center point as the cut line location.

You are now going to create a section cut. Select the offset section cut icon. It is located under the offset section view icon. This will allow you to define cut lines but instead of generating a section view it will generate a section cut. Define your cut lines as shown below. The numbers show the order of selection. Make sure you double select your last location.

Position your view to the right of the Top view as shown below.

You should notice that the section cut does not show any geometry other than what the cut line actually touches. That is the difference between a section cut and a section view. Make the Front view active. You can do this by double selecting on the Front view. You are going to create an aligned section view using the Front view. Select the aligned section view icon. It is located under the offset section view or offset section cut icon. With this option you can create cut lines that are not parallel. Define your cut lines as shown below. The numbers show the order of selection. Make sure you double select your last location.

Position the view down and to the left of the Front view. The view is positioned normal to one of the cut lines.

Change the Properties of the aligned section view to not show Hidden Lines. It should appear similar to the diagram shown below.

You have the option of creating aligned section views or cuts, however this exercise only shows you the option of creating an aligned section view. Creating an aligned section cut is done in the same manner except you use the aligned section cut icon. Feel free to try the option out on your own. The next item that will be discussed in terms of section views and cuts is that you have the option of using a planar surface or an actual plane from your 3D part to define the cut line. Make sure you have the part window and the drawing displayed with Tile Horizontally. This will enable you to see what is going on in both windows. Make sure the Front View is still active. Create a plane in your part that is offset from the xy plane 0.25 inches. Go back to your drawing and select the offset section view icon. You may have to update your views since you made a change to your part. If you do just select the update icon. Select the created plane from your part. Notice the cut line automatically appears in your Front view. The cut line is not associated or linked to the plane and can be modified in the drafting workbench. © Wichita State University

Position the view under the Front view as shown below.

You can also create a sketch in your part that can be used to define a section line. When you use a sketch to define a section line, the section line is associated or linked to the sketch. If you want to modify the section line you would need to open the part and modify the sketch and then update your views. If you erase the sketch that was used to define the section line, then the section line would no longer be linked and it would be converted to a normal section line that could be modified within the drafting workbench. Save your drawing and close all documents.

Detail Views A detail view is a partial view of a part that is usually at a higher scale to make it easier to see. CATIA allows for the creation of four different detail views. You can either use a circle or a profile callout. Besides choosing what you want to use as a callout, you can either create the detail view so that it uses the 2D projection to determine the detail view or it can generate the view from the 3D definition. The quick detail options use the 2D projection to generate the view. Open the Detail Views drawing. Make sure you open the CATDrawing and not the CATPart. You should notice that the Front view is active since the outline is red. You are going to create a couple of detail views to draw attention to various areas that may be hard to understand with the current views. Select the quick detail view icon. It is located under the detail view icon. This will allow you to define a circular callout to define the detail view. Since you are using the quick option this will utilize the 2D projection to define the detail view. A Tools Palette window appears. This window appears on a variety of icons and will show the available options for the icon selected. In this case you can specify an exact radius for the callout. You are going to define the radius by selecting a location instead of keying in a value.

Select the center of your circle and define your radius as shown below. This will define the area that is used in the detail view. A preview of the area of the view should appear for you to position on your sheet.

Creating Views, Page 49

CATIA Drafting

CATIA® V5R14

Position the detail view to the right of the Front view. You should see the view appear similar to the one shown below. Also you should note that view defaulted to a scale of 2:1. You can adjust this scale by changing the properties of the view.

Notice that the view name corresponds with the letter assigned to your circle callout. This was created using the quick detail option. Next, you will create a detail view not using the quick option. Make the rightmost isometric view active. You can do this by double selecting on the view. Select the detail view profile icon. It is located under the detail view or quick detail view icon. This option will let you use a profile to define the callout. You can do this by selecting the endpoints of lines defining the profile. You can either close the profile yourself or you can double select to end the profile definition. If you double select, the profile will close automatically using a line connecting the last and first point defined. Define the profile as shown below. The arrows point to the corresponding endpoints.

CATIA® V5R14

Position the view to the right of the isometric view. It should appear similar to the diagram shown below.

Notice that this view does not show the profile line past the edges of the part, in other words, the detail view is trimmed to the part edges. This is because the view is using the 3D definition to define the view instead of the 2D projection. You will now create two other detail views to better illustrate the difference between the quick detail view and the regular detail view. Make the Bottom view active. Select the detail view icon. It is located under the detail view profile icon. This will allow you to define a circular callout. The Tools Palette window appears. Define a circle as shown below.

Position the detail view to the right of the Detail B view. It should appear similar to the diagram shown below. Once again, notice that the view is trimmed to the edges of your part. Unlike the quick detail option that you used the first time which shows the entire circle.

Make the leftmost isometric view active. Select the quick detail view profile icon. It is located under the detail view icon. This will allow you to define a profile to use as the callout. Define a profile similar to the one shown below.

CATIA® V5R14

Position the view above the Detail C view. You should notice that the profile definition does not stop at the edges of the part, instead the entire profile is shown. This is because the quick options use the 2D projection and not the 3D definition.

Hopefully this exercise gives you a good example of the difference between the various detail view options. Save your drawing and close all documents.

Clipping Views Clipping views are similar to detail views in the way they can be defined. You have the option of either using a circle or a profile to define the clipping area just like the detail view. However the difference is that a clipping view actually changes the current view to just contain the clipping area. This option is used when the whole part would be too large and you are only interested in a section of the part. By default the clipped view will maintain its scale ratio. Open the Clipping Views drawing. Make sure you open the CATDrawing and not the CATPart. You should notice that the Auxiliary view is active since the outline is red. Select the clipping view profile icon. It is located under the clipping view icon. You are going to define a profile that you want the auxiliary view to contain instead of it showing the entire part. Define the profile as shown below. This is done the same way as you defined a profile for a detail view.

Notice that the view automatically changes after you finish defining the profile. It is important to understand that this did not create a new view but changed the existing view to only show the clipped area. The clipping view option will do the same thing except you define a circular area instead of using a profile. Save your drawing and close all of the documents.

Broken View A broken view is used when you have a long section that is not important to be seen in the view. This option will allow you to define the two ends of the break and then it will modify the view so that section will not appear. Breakout lines are generated to show where the breaks occur. Open the Broken View drawing. Make sure you open the CATDrawing and not the CATPart. You should notice that the Front view is active and that the Left view extends past the sheet. You are going to use the broken view option to modify the Left view to show the two ends of the beam leaving out the middle section. Make the Left view active. Select the broken view icon. You are going to define two break lines that will define the area to remove when modifying the view. Select inside the beam edges at the location shown below. Once you select the location you can either create the broken view to break horizontally or vertically. In this case you want the break to be vertical.

Select above the previous location. You will now be able to define the other break line so that it can remove the area between them. Select inside the beam edges at the location shown below.

Select outside the view on the sheet. The broken view is generated. However the view is still partially off the sheet and the label is to the right of the actual geometry.

Drag the text underneath the geometry. You can drag the text if you hold the first mouse button down while on the text. Drag the view over to the right until it is completely on the sheet. You can drag the view by holding the first mouse button down on the frame of the view. The finished drawing should look similar to the one shown below.

You can define more than one break in a view but it has to be in the same direction. That would be useful if there was a pocket removed out of the middle of the beam and you wanted to break the view in order to show the two ends and the pocket definition. Save your drawing and close all documents.

CATIA® V5R14

Breakout View A breakout view is used when you have a current view that needs to have a section removed in order to better see the definition that is behind the section. Hidden lines could be used to show the definition but sometimes it is not very clear because of the number of hidden lines. You can define a profile of the section that you want removed in the view and then you have the option of using a 3D viewer to define the depth of removal using another view. This will modify the existing view to show the breakout. Open the Breakout View drawing. Make sure you open the CATDrawing and not the CATProduct. You should notice that the Front view is active. There are two top views, one with hidden lines and one without. The one with the hidden lines is a little congested because of the hidden lines of the bracket. In this particular case you are more concerned with what the top view looks like without the top of the bracket. Make the left Top view active. Select the breakout view icon. It is located under the broken view icon. You are going to define the break out area to remove when modifying the view. Define the profile as shown below. The Tools Palette window appears allowing you to specify the length and angle of each linear section. You can define this profile exactly the same way as you defined a profile using the detail or clipping option.

CATIA® V5R14

After you define the profile a 3D Viewer window should appear.

The 3D Viewer allows you to see a preview of the depth of the removal and you can use the orange line to define the depth of the cut. If you use the line in the 3D Viewer it is not linked to any geometry and is only an approximate location. You can also define the depth by selecting an element in another view and it will be linked to that element. In addition, you can specify a Reference element and a Depth using the available options. Animate

Allows the 3D Viewer window to change as you position your cursor in another view.

Depth Definition Reference element

Specifies the element that you want to use as the depth and you have the additional option of defining a Depth from that element.

Select the Animate option in the 3D Viewer window. Move the cursor to the Front View. Notice that the image changes to show the Front view orientation.

Select the bottom dashed line of the bracket as shown below. This will define the depth of the breakout.

Select OK. Even though the position may change as you move the cursor to the OK button it should keep the selection specified. The breakout view takes affect and the Top view changes. It should appear similar to the diagram shown below.

This option can be very useful to show an area of internal material, rather than using hidden lines. You should notice that this option only modifies an existing view just like the broken view and clipping view options. Save your drawing and close all documents. This finishes the discussion on creating views individually. You will now investigate the configuration options available.

CATIA® V5R14

Configuration of Views There are four options to create a configuration of views on your sheet. Three of them are preset configurations and the other one is a creation wizard that lets you define the configuration. The three that are preset are Front, Top and Left; Front, Bottom and Right; and All views. You will experiment with the presets and then create your own configuration using the wizard. Open the Configuration part. You will be creating views for this part. Start a new drawing with an empty sheet using the same options as before. You do not want any views in the initial drawing. Change your window configuration to be Tile Horizontally. Select the front, top and left icon. It is located under the view creation wizard icon. You now must select the part that you want to use to create the views. Select the top circular face of the part as shown below. You should see a preview of the three views in the drawing.

You can move your cursor inside the other view boxes and it will show you the preview of that view. You also have the option of orientating the views using the blue orientation circle.

Locating Views On large drawings there are times when it is hard to tell where a corresponding detail or section view is located. Also, it can be hard to tell where the parent view of a detail or section view is located. A couple of options to help you locate views will be covered. Press the third mouse button while on the section line callout in the Front view. Options appear. Select the Locate Resulting View option. The corresponding section view is shown. Press the third mouse button while on the Section view. Options appear. Select the Locate Reference View option. The parent view of the section view appears, which is the Front view. View Names You are going to move around some of the view names so that they are in positions that are easier to read. There are a lot of properties that you can change involving the text but they will be covered later. Press and hold the first mouse button while on the view name for the Front view and drag the name down away from the section line. This should make it easier to read the view name along with making it easier to see the section arrow. In the Clipped view, select the view name and press Delete. You are going to have CATIA recreate the view name. Using the third mouse button select on the Clipped view and select Clipped view object, Add View Name.

Restore Deleted You can delete elements from your views after they have been generated in order to develop a better looking view. Sometimes you may accidentally delete an element that you wanted to keep and did not realize until it was too late to undo. The restore deleted option allows you to have the view get regenerated in order to restore that element. In your Right view delete one of the vertical lines in the middle. Since you deleted the element it is not possible to get it back other than by using the undo option. Save and close your drawing. Open your drawing again. Notice that the undo option is no longer available. However, using the Restore Deleted option you can have the view get regenerated with that line. Using the third mouse button select on the Right view and select Right view object, Restore Deleted. A Restore deleted elements window appears.

Select OK. The window closes and the update icon is available. Select the update icon. This will update the views restoring the deleted element. You should note that without using the Restore Deleted option and only using a force update command the line would not have been regenerated.

Updating Views You are going to modify the View Review part that was used to create this drawing and then update the views in order for them to rebuild with the modification. When updating views, you can specify which views you want to update by selecting them from the tree, pressing the third mouse button and selecting Update Selection. The views that still need to be updated will show the update symbol on the icon in the specification tree. Open the View Review part. Make sure you leave your drawing open at the same time. Modify Hole.3 to be 0.5 inches in diameter. Go back to the drawing window. Notice that the update icon is available. Since the part has been modified, the update icon is available but it does not update automatically. Select the update icon in the bottom toolbar. All the views that contained that hole are updated with the new size. If you isolate a view then you will not have the option of updating the view when modifications occur to the part. Using the third mouse button select on the Right view and select Right view object, Isolate. The icon next to the view changes so you know the view is isolated. You should note that once a view has been isolated it cannot be associated again without recreating the view. Most dress up elements will be preserved but they will no longer be associated to the part geometry. Go back to the part window and modify Hole.2 to be 0.375 inches in diameter. Go back to the drawing window and update the views. Notice the hole changed in all the views that contain the hole except the Right view. This view is no longer associated with the part geometry. Close the View Review part without saving. Notice that the views in the drawing remain unchanged and that there is no update option available even though you did not save the changes you made to the part. Save your drawing. A Save warning window will appear telling you that your drawing points to a modified drawing. Select OK. The window closes. Close your drawing. Another warning window will appear. Select Yes to this window. The window closes along with your drawing. Reopen your drawing. Now the update option is available. Select the update icon. The views get updated except for the isolated Right view. You will investigate the effect that locking a view has on the update process. Under the properties of the Front view toggle the Lock View option on and select OK. You should notice a little lock symbol on the view in the specification tree. Modifying Views, Page 82

Open the View Review part. Make sure you leave your drawing open at the same time. Modify Hole.3 to be 0.5 inches in diameter. Go back to the drawing window. Notice that the update icon is available. Select the update icon in the bottom toolbar. A Locked view window appears. It basically states that the locked view was not updated with the change because it is locked. The other views updated except for the isolated Right view.

Select OK. The window closes. Change the properties of the Front view to be unlocked. The update icon is available again. Select the update icon in the bottom toolbar. The Front view updates with the change. Close the View Review part without saving. You will have to save and close your drawing in order to reopen it and update it to the current state. Save and close your drawing and then reopen it and update it. This seems like a pain but in reality you probably won’t be making changes to a part and then update your views and then close your part without saving the changes. But it is important to realize what could happen to your views if you are not careful.

Dimensioning This section will discuss the various methods of creating and generating dimensions. You will also explore the various options you have to modify the dimensions. Creating Dimensions Dimensioning in CATIA V5 can be a little overwhelming due to the amount of options but once you get a good understanding of the options it is fairly easy to dimension. This exercise will focus on creating the dimensions manually. Open the Basic Dimensioning drawing. You are going to use this simple drawing to experiment creating dimensions. There are four explicit dimension options that will be covered first. These options are used explicitly to create that type of dimension. Length/distance

Radius

Angle

Diameter

Length/distance Select the length/distance dimensions icon. It is located under the dimensions icon. This will allow you to create a length or a distance dimension. The Tools Palette window appears. These options are covered a little later and are also available by pressing the third mouse button. In the Isometric view select the line shown below. A length dimension appears. Before you position this dimension you are going to look at some of the options that you can adjust before creating the dimension.

Tolerance Next to the dimension line options there are two boxes for tolerance. They are described below. Tolerance Description

Tolerance

As you can see there are many types to choose from. In this class you will primarily use TOL_NUM2 and TOL_RES2. TOL_NUM2 is for over/under tolerances and TOL_RES2 is for limited tolerances. The second box has some predefined values but you can key in your own. In the first box select TOL_NUM2 and in the second box select +-0.05. Your next dimension will have tolerance attached to it. Create a dimension of the distance between the leftmost vertical line and the rightmost vertical line in the Front view. The tolerance should appear with the dimension. You may have to drag the Front view name out of the way.

In the tolerance box key in +0.05/-0.03. You have the option of keying in your tolerance value and then it will be added to the list in case you want to use it again within this drawing. If you want the tolerance to be the same and use the plus/minus sign then you can key in the tolerance as follows: +-0.03.

Numerical Display Similar to the tolerance options there are two numerical options. They are described below. Numerical Display Description

Precision

These descriptions represent different units and styles. NUM.DINC will set the unit to inches using the decimal system. NUM.DIMM will set the unit to millimeters. DISTINCH will set the unit to inches and be followed by a ” to indicate it is in inches. Those are primarily the ones that will be used in this class. It is important to note that it does not matter what units you have your model set to using Tools, Options, since the numerical display description determines what units your dimensions are in. The precision box determines how many decimal places to use for the dimension. You can select from one of the provided options or you can key in your own precision. Make sure the numerical display description is set to NUM.DINC and change the precision to 0.001. You will create another dimension utilizing these parameters. Create a dimension in the Front view between the vertical center line and the left side. Notice that three decimal places appear on the dimension.

Modifying Dimensions There a lot of ways you can modify your dimensions. One method is to use the options in the top toolbar. Up until now you have used those options to set the parameters for dimensions you were getting ready to create. You can also turn on some options under the pull down menu Tools, Options, Mechanical Design, Drafting, Manipulators. Another option is to change the properties of the dimension using the third mouse button. All of these ways will be explored in this exercise. Open the GDTfinished drawing. This should be almost identical to your GDT drawing that you just saved. However, it is probably better to use this one so that all of the dimensions are setup as expected for the exercise. The Section view should be the active view. Top Toolbar The first method of modifying dimensions that you will explore will involve the top toolbar.

Select the 2.225 dimension at the top of the Section view. If you look at the top toolbar you should notice that the parameters have changed based on what the dimension has assigned to it. You can modify any of the parameters in the same manner as you set them earlier. The difference is that this time it will only affect the selected dimension. Change the tolerance from +-0.005 to +0.003/-0.005 and press Enter. The tolerance on the dimension changes. Change the precision from 0.001 to 0.0001 and press Enter. Notice the number of decimal places changes on the dimension. Select off the dimension on the sheet. Notice that the top toolbar reverts back to the settings it had before selecting that dimension. You can also change more than one dimension at a time. Select the 2.2250 and the 1.395 dimension. You will have to use the Ctrl key to select both dimensions at the same time. Change the tolerance to +-0.003 and change the precision to 0.001. Notice that both dimensions change to that tolerance and to that number of decimal places. Select off the dimensions on the sheet. Select the 2.225 dimension and change the dimension line style to two part leader. The dimension changes to have a leader with two parts. Change the numerical display description to DISTINCH. The dimension appears with ” representing inches. Change the tolerance description to TOL_RES2. The dimension changes to a limited dimension. © Wichita State University

Modifying Dimensions, Page 141

CATIA Drafting

CATIA® V5R14

Change the dimension line style back to regular, the numerical display description back to NUM_DINC and the tolerance description back to TOL_NUM2. The dimension should return to its original parameters. You can also change the tolerance for the 2.225 and 1.395 dimensions back to +-0.005. You are now ready to explore another option to modify dimensions. Pull Down Menu Tools, Options This method allows you to turn on certain manipulators to modify your dimensions either as you are creating them or after they have been created. Go to pull down menu Tools, Options, Mechanical Design, Drafting and the Manipulators tab. You can toggle the manipulators to be on during Creation or Modification by selecting the appropriate boxes.

Even though you can move the value without the manipulator, it can be useful when you are moving a value that has an extension or leader. The dimension line move options are also very useful when you are trying to position a radius or diameter dimension. Toggle all the options on under Modification. When you select a dimension that has already been created these options will appear around the dimension. Select OK.

Drag the white box at the bottom of the right extension line up adjusting the blanking. Drag the box down to an appropriate distance and let go. With the manipulators turned on it is very easy to modify your dimension. You can also turn these manipulators on during creation so you make these changes as you create a dimension. You should notice that both extension lines get adjusted when you use the manipulators to change the blanking or overrun. If you only want to adjust one of the extension lines then you can hold down the Ctrl key and select the box. This will only adjust the extension line selected. You also have the option of double selecting on the box and keying in a distance that you want either for both extension lines or just the one.

Delete the text before and after the 2.225 dimension. You can do this by selecting on the appropriate red triangle and removing the text and select OK. Select off the dimension on the sheet. This releases the dimension. You can also modify a geometrical tolerance by double selecting on the frame. Geometrical Tolerance Double select on the parallel geometric tolerance located at the bottom of the Section view. The Geometrical Tolerance window appears just like it does when you create a geometrical tolerance. You can make changes and then select OK when done. Do not make any changes at this time.

Analysis You have the option of performing a dimensions analysis and it will show what dimensions have bad placement. Open the Dim Modify drawing. The drawing should contain four views with the Front view active. You should also notice that some dimensions have already been placed on the drawing. You are going to analyze these dimensions to see if you have any problems with the placement of the dimensions. Select the dimensions analysis icon. You may have to turn that toolbar on in order to see the icon. You can do this by choosing the Analyze option under the pull down menu View, Toolbars. The Analyze window will appear. This performed an analysis of your active view, in this case the Front view. Notice that it found 3 elements badly placed. You have the option of choosing an optimized list.

Total number of elements in the current list The number of elements that are badly placed. Number of the pointed element

As you scan through using the Scanner it will show you which element number you are looking at.

Scanner

Allows you to step through the list one at a time forward or backward, jump to the end or beginning and to update the list as you make changes.

You should also notice that dimensions in the view are color coordinated. The highlighted elements are the ones that are badly placed. Notice that when two items interfere with one another both are counted as being badly placed. The optimized list takes this into account and only counts that as one element. Switch the option to Optimized list with the annotations badly placed. The Total number of elements in the current list changes to 2 instead of 3. Sometimes this is preferred although as you correct a problem with them listed either way the number will change after you update the analysis. Switch the option back to the List with the annotations badly placed. You are now going to scan through the list and make changes as you go.

Select the next icon until you get to the view name. The view name interferes with the 2.75 dimension. Move the view name below the 3.25 dimension. This will locate the view name at the bottom of the view out of the way of all dimensions. Select the update icon in the Analyze window. Now you are down to two elements that have problems. One is the 2.00 radius and the other is the 2.75 dimension. The reason it thinks there is a problem is that if the dimension line of the 2.00 radius went to the center of the circle then it would interfere with the 2.75 dimension. Select the next icon until you get to the 2.75 dimension. Notice a circle appears on top of the 2. This is where the center point of the circle is located. You need to move the dimension off of this center location. Move the 2.75 dimension down a little so that it does not interfere with the center location and select the update icon in the Analyze window. The number of elements changes to 1. Select the next icon. Notice that the radius dimension still thinks it interferes with the 0.75 dimension. Notice the circle notation on the extension line of the 0.75 dimension. You will modify the blanking of the 0.75 dimension so that it stops before that interfering location. Select OK. This exits the Analyze window. Modify the end of the .75 extension line to stop before that interfering location. You can do this by using the manipulators or the properties of the dimension. Select the dimensions analysis icon again. It now states that there are no problems with your placement of the dimensions. Depending on your company’s standards it may not be necessary to make the last two adjustments. Select OK to exit the window. Activate the top view and perform a dimensions analysis. There is only one bad placement in this view. Modify the placement until there are not problems and exit the Analyze window. You fixed all of the bad placements manually, however there are some tools that assist you in placing and aligning dimensions. You will explore those options next. Close all documents. You do not need to save this drawing. Note: The analysis option can also be accessed through the pull down menu Tools, Analyze.

Positioning There are some positioning tools that can help you position your dimensions properly. These can be extremely useful when you are working with generated dimensions as you will later in this course. In order to see these icons you may have to turn on the positioning toolbar. Turn on the Positioning toolbar. You can do this by choosing the Positioning option under the pull down menu View, Toolbars. Open the Dim Modify drawing. This will open the same drawing that you used last time without the modifications. Select the 1.50 and the .75 dimensions in the Front view. Make sure both are selected. Select the line-up icon. This will allow you to line-up your dimensions automatically without having to do it manually. You also have the option of using the third mouse button and selecting Line-Up. You have the option of specifying a reference line or to select a reference from free space. Select the rightmost vertical line in the Front view. This will use that line as the reference element. The Line Up window appears.

Make sure that the Only organize dimensions into systems option is off and enter 2.0 for the Offset to reference and 2.0 for the Offset between dimensions and select OK. The two dimensions are positioned. The 0.75 dimension is one inch from the reference element. The 1.50 dimension is one inch from the 0.75 dimension. If you would have had the Only organize dimensions into systems option on then the 0.75 dimension would not have moved and the 1.50 dimension would have been an inch from the 0.75 dimension. The reason they are only one inch apart is because the view scale is 2:1. Select the .75 and the 1.00 inch dimensions. Select the line-up icon. Select the leftmost vertical line in the Front view. This will use that line as the reference element. Make sure the Only organize dimensions into systems option is off and enter 1.0 for the Offset to reference and 1.5 for the Offset between dimensions and select OK. The dimensions move. The line-up icon works very well to position dimensions uniformly without you having to manually do it. The other line up option is the align into system icon. This icon will use the default settings that are defined in pull down menu Tools, Options, Mechanical Design, Drafting, Dimensions tab. It will align the dimensions just like the line up icon except it will always have the Only organize dimensions into systems option on. Therefore the first dimension will not move and the spacing between the other dimensions is determined by the default settings. If everything is set up correctly this can be a very quick way of aligning dimensions. There is another option that works well to position dimensions as well called dimension positioning. The dimension positioning icon is extremely useful when you are working with generated dimensions. Activate the Top view. You are going to use the dimension positioning icon to automatically position all your dimensions.

Interruptions Interruptions are used to break or limit an extension line or lines so that they do not interfere with your geometry or other annotations. This exercise will demonstrate how to create and remove interruptions. You can either use the icon or you can use the third mouse button and under the object name there are interruption options. Select the create interruption(s) icon. It is located under the re-route dimension icon. It wants to know what dimension you would like to create the interruption on. Two new icons appear in the Tools Palette.

Creates an interruption on one extension line Creates an interruption on both extension lines You can create an interruption in all of the extension lines at the same time or you can choose to create an interruption in just the one extension line. You have to remember to select the appropriate icon in the Tools Palette before defining the interruption. Select the add interruption on one side icon in the Tools Palette. create an interruption on the left extension line.

Update You will now see the effects of making changes to your part and updating the views. Open the Dim Modify part. Keep your drawing open. In Sketch.1 change the 2.75 constraint to be 2.5 and exit the sketcher. You have now changed your part and the views in your drawing will need to be updated. Switch to your drawing. Notice the update icon is available. Select the update icon. Notice your dimensions automatically adjusted. Switch back to your part and modify Sketch.1 so it does not have the 1.5 inch wide opening as shown below.

Switch back to your drawing and update the views. Notice that two of your dimensions in the Top view change to a pinkish color. This is signifying that they cannot be updated. The reason is obvious, the elements that they were dimensioning are now gone. The color of a dimension means different things. There is an analysis display mode option that can be turned on and off. It is located in the Tools toolbar. If it is on, then you will see the colors change as the status of a dimension changes.

Generating Dimensions Generating dimensions is a quick way of creating dimensions that have already been defined with constraints in your Part. There are two options to generating dimensions, either all at once or step by step. There have been some bugs in the software, therefore the appropriate dimensions may not appear highlighted when doing analysis after generation. However, the generating portion is working, therefore it should not cause the exercise to fail. Open the Generate Dim drawing and part. You are going to look at the constraints of the part first to get an idea of what is happening when you generate dimensions. Switch to the part and look at Sketch.1 and its constraints. Notice that the rest of the elements are fillets and holes. Exit the sketcher and switch back to the drawing. Before you generate the dimensions all at once you are going to turn on the option to filter before generation. This will allow you to specify the filters you want to use before generating the dimensions. Go to pull down menu Tools, Options, Mechanical Design, Drafting and the Generation tab. Turn the Filters before generation option on and select OK. You should also notice that the Analysis after generation option is already selected. Select the Front view. It should appear highlighted. By selecting a view or views before selecting the generate dimensions icon, dimensions will only be generated for that view or views.

This option is very nice to get a beginning position for all of the dimensions, however you may still have to do some modifications in order to clarify the dimensioning of your part. You also may have to add additional dimensions in order to finish your drawing. Your generated dimension can be used to control the 3D constraints. This can only occur if the option under Tools, Options is set accordingly. This can be a very dangerous option so you will be introduced to it and then you will set the option so it cannot be done.

You should notice that there are some dimensions that you do not want and some dimensions that you would prefer to be in a different view. If you specify a .40 TYP for the thickness of the part then the other .40 dimensions and the 1.15 radius dimension are unnecessary.

You can take care of some of these problems by generating the dimensions step by step instead of all at once. The step by step option allows you to specify whether or not you want to keep a dimension and you have the option of transferring a dimension to another view. The disadvantage is that it can take longer since it is letting you interact with the generation process. Close the drawing and the part without saving and reopen them.

Creating Symbols Symbols are another method to convey information about a drawing to other users. The symbols that you can create are balloons, roughness symbols, welding symbols and welds. You can also create a datum target but that was covered in the dimensioning section. Balloon Balloons are normally used to point out part numbers especially when shown in an assembly view. Activate the Top view. Select the balloon icon. It is located under the text or text replicate icon. You can now define a location for the head of the arrow. Select on the bottom horizontal line on the left side. You can now select a location for the balloon and its text. Select down and to the left. The Balloon Creation window appears.

Key in 401 and select OK. Notice the balloon automatically resized for the text to fit inside it. This is very similar to text with a leader and a circular frame. Select on the balloon. Notice the box at the head of the arrow. You have a lot of the same options for this leader that you had with leadered text. In the top toolbar you should notice that the frame option shows the circle frame. Many times companies will have a standard size balloon that they will want you to use. You can access this standard size by changing the frame to use the fixed size frame instead.

Roughness Symbol This exercise will only show you how to create a roughness symbol it will not explain what all of the options mean in terms of roughness. A roughness symbol states what type of roughness a particular side can have based on its material removal process and other parameters. Select the roughness symbol icon. Select at the bottom of the left vertical line in the Top view. The Roughness Symbol Editor window appears.

The following diagrams show the available options under each arrow.

The first area labels various values that you would key in. The second column represents what type of material removal can be used. The fourth column represents the lay direction. Change the first option to Rmax with a .25 value next to it. Change the second option to be the full triangle to signify material removal by machining. Change the fourth option to have a lay direction that is perpendicular. © Wichita State University

Markup These options are used to markup your drawing. A lot of these options can be generated by modifying the properties of your view to show the respective elements. However, there may be times that you want to manually create these markups. They are very useful when you are creating your drawings from scratch instead of having them be generated from 3D. Center lines and Axis lines Open the Markup drawing. You should see three views, one of them is a section view. Notice that there are not any center lines or axes shown in the views. You are going to manually create them. These views are not linked to a part. The geometry is stand alone 2D geometry. You are going to provide the markups. Zoom in on the Top view so that you can see the circles easier. You are going to create center lines. Hide the section line. This will allow you to see the center lines better. Select the center line icon.

This will allow you to create center lines.

Select the larger circle on the right side. Center lines appear. You can adjust the length of them by selecting them and dragging one end of the center lines. Select both of the smaller circles on the right and then select the center line icon. Notice that center lines are created on both circles automatically. You can also create center lines that are associated to another element. Select the center line with reference icon. It is located under the center line icon. This will allow you to create center lines that reference another element. Select the larger circle on the left side. You can now select a reference. Select the smaller circle in the middle. The center lines appear. Notice that the vertical center line is not actually a line but a curve since it is referencing the circle. Select both of the smaller circles on the left and then select the center line with reference icon. Select the smaller circle in the middle. The center lines appear on both circles referencing back to the center circle. You can also create thread notations on your circles. Select the thread icon. It is located under the center line or center line with reference icon. This will allow you to create a thread notation on a circle. Select the smaller circle in the middle. The thread notation appears. Similar to the center line option, you can create thread notations that reference another element as well. Select the undo icon.

Select the smaller circle in the middle. You now need to define a reference element. Select the lower right corner radius. Notice that the thread notation appears with the one center line curved and the other pointing back at the center point of the corner. Delete the center lines on the two small circles on the right. You are going to create an axis line along with center lines between these two circles. Select the axis line and center line icon. It is located under the center line or thread with reference icon. This will allow you to select a couple of circles to create an axis line and center lines between them. Select one of the small circles on the right and then the other. Center lines are created on both circles with an axis line connecting the two circles. The Top view should appear similar to the diagram shown below.

Zoom in on the Front view and activate it. You are going to create some axis lines on this drawing. Select the axis line icon. It is located under the center line or axis line and center line icon. You can select an element that will create an axis line such as a line representing a cylinder or you can select two reference lines and the axis line will be created in the middle of them. Select one of the vertical dashed lines in the middle. This defines one reference line. Even though this line represents the side of a cylinder the axis line does not appear because CATIA only sees the element as a line. If this view was linked back to a part that has this hole then CATIA would realize that this is an edge of a cylinder and an axis line would have been created. Select the other vertical dashed line in the middle. An axis line appears in the middle of the cylinder.

Adjust the length to extend past the edges of the part. You can adjust the length by selecting on the line and then dragging one of the white boxes at the end of the line. If you only want one of the ends to change then you need to hold the Ctrl key down when selecting the white box. Create axis lines in the center of all the rest of the holes by selecting the two lines that represent the edges of the cylinder. Adjust the length of these lines to extend past the edges of the part as shown below.

Activate the Top view. Select the axis line icon. Select the top right horizontal line and the bottom left horizontal line. An axis line appears. Adjust the size to go past the ends of the part. This is a good way to create a center line on your drawing.

Area Fill Area fills are useful to finish section views that were not generated from 3D. They can be used any time and there are patterns that an area fill can use to represent different materials. You can manually create an area fill using generated elements as well but it is not commonly needed since the section view and cut will automatically generate the area fill for you. Activate the Section view. You will use the area fill option to fill in the necessary areas of the section view. Delete the horizontal dashed lines. You do not want these lines to appear in the section view. Select the area fill icon.

The Area detection window appears.

CATIA® V5R14

Modifying an Area Fill You can modify the pattern that an area fill uses as well as modifying the pattern that gets generated when you create a section view or cut from a 3D part. You can modify a pattern either by changing its properties or by using the top toolbar. Properties Make the Section view active. You are going to change the properties of the pattern. Go to the properties of the pattern shown below. Remember you can go there by using the third mouse button.

The following Properties window corresponds to the properties of a pattern that was manually created not generated by a section view or cut of a 3D part. However, the only difference between this window and the other is a Material area which would appear at the bottom. Since an area fill that is created manually is not tied to a part then there is no need for the Material area. If the pattern is generated from a 3D part then the pattern has the capability to be linked to the material of the part.

You are going to change the properties of the pattern so that it fits into the area better. Go to the properties of the pattern. You need to change the Pitch. Change the Pitch to be 2 and select Apply. Notice the pattern displays more dots. Change the color to be a pinkish purple and select OK. Your pattern now appears with that color of dots. Now that you have modified the two patterns on the right, you want the two patterns on the left to be the same. You can use the top toolbar and change the properties of each pattern so that it matches the right side or you can copy the settings of the one pattern to the other. Select the big pattern on the left. You must select the pattern that you want to copy settings to before you select the icon. Select the copy object format icon. You can now select the pattern which acts as the reference. In other words the pattern whose settings you want to use. Select the big pattern on the right. The pattern on the left changes to use the same pattern as the one on the right. You need to do the same thing but use the smaller patterns. Select the small pattern on the left.

Graphical properties The top toolbar contains graphical properties. You just used a couple of the options but you will now look at the remaining ones.

The remaining ones are color, thickness, line type, point type and layer. You will not mess with the layer option at this time. The other two options are the copy object format and the change pattern icons that were used earlier. Select on the left vertical line of the center hole in the Section view. The graphical properties change to display what the element currently has assigned to it. Change the color to a dark blue. The line changes color. You may not be able to see it because the line is highlighted. Select off the line and notice the color changed. You should also note that the graphical properties on the top toolbar revert back to the color black. The top toolbar shows the graphical properties of all new geometry. When you select on a particular element it changes to show you the graphical properties assigned to that element. Select the line again. The graphical properties show you what is assigned to the line. Note the blue color. Change the thickness to 6 and the line type to dashed. The line changes. Select off the line. You are now going to copy these settings to the other vertical line representing the other side of the hole. Remember you need to select the receiving element first. Select the other vertical line representing the center hole. Select the copy object format icon. Select the blue dashed line. The vertical line changes to match the other one. Your Section view should appear similar to the diagram shown below.

Arrows The last type of markup you can perform on a drawing is the creation of arrows. This option is not commonly used since normally you will use text with a leader to point out items of interest. Select the arrow icon. The arrow option allows you to define an arrow by specifying the tail of the arrow and then the head. Select down and to the left in the Section view. You now need to define the head location. Select on the line at the bottom of the hole. The arrow is created. You may have to change the symbol to be a filled arrow.

Select on the arrow and change the graphical properties so that the arrow is red. You should have noticed that the arrow has a box at each end when you select it. Those boxes will allow you to change the appearance of the arrow. Select on the arrow again and press the third mouse button while on the box at the tail of the arrow. The following options appear. These options work the same as they did with leaders.

Assembly You are going to create views using an assembly (product) as well as generate views of the parts that make up the assembly. You will be using a scene that was created, showing the exploded assembly and you will learn how to generate a bill of material within your drawing. Creating an isometric view Creating views for an assembly is not much different than creating views for a part. Open the Views Assembly product from the Views Assembly directory. This is an assembly of a hand drill and it contains a scene of the part exploded. Start a new drawing with an empty sheet, the settings should be ASME Standard, E ANSI Sheet Style, Landscape orientation. Change the windows to be Tiled Horizontally. You should be able to see the sheet and the product. Select the isometric view icon and select the product anywhere. Notice the entire product is going to be used. Create the view with the following orientation and change the scale to be 0.5. As you can see it is not any different than creating an isometric view of a part.

CATIA® V5R14

Generate balloons Select the generate balloons icon. It is located under the generating dimensions icon. Balloons appear on the view pointing at the individual parts. The reason they were generated is because in the product, numbering had been applied labeling them with letters. Note: You can change what gets generated in the balloon under Tools, Options. In the Mechanical Design, Drafting, Annotation and Dress-Up tab you can specify whether you want to use the Numbering, Instance Name or Part Number. In this case you are using the Numbering. Move the balloons around to look similar to the diagram shown below. Next you will generate a bill of material.

Note: There is an option under Tools, Options that will generate a balloon for each instance of a component. This option is in the Mechanical Design, Drafting, Generation tab. If this option is on then every instance of a component will get a balloon, if it is off then only one instance of each part will get a balloon. This only applies when you have a part instanced multiple times within an assembly. If will not have an effect is this example.

Views of parts of an assembly There may be times that you will want to create views of the various parts of an assembly instead of or in addition to the views of the assembly. This is easily done by selecting a part of the assembly instead of the complete assembly. Insert a new sheet into your drawing. You are going to create views of the various parts of your assembly. Change the scale to be 0.5. Using the view creation wizard define a layout of Front, Top, Right. Before selecting the part from the display area you will want to select the part from the tree. Go to the product window. Select Ergo Case from the specification tree. This will allow you to create views of the case only. Select on the side face of the case to define a plane. Create the views and position them as shown below.

Repeat the steps for the Drive Gear. The views are created. Repeat the steps for the Large Drill Bit, Large Chuck and the Output Gear. You may have to expand the subassembly Output Assembly in order to select these three parts. You do not need the Top view for these three parts. Position the views as shown below.

You are going to create an isometric view of the subassembly Handle Assembly and views of its corresponding parts. Use the isometric view icon and select the Handle Assembly in the product window and define a plane. Use the side face of the case. Create the view. Using the same steps as discussed earlier create Front, Top, and Right views of the Handle Arm and the Handle Knob. You may have to expand the subassembly Handle Assembly in order to select these two parts.

View Links Every view that is generated from a 3D document is linked to that document by default. Earlier you saw how you can make modifications to a 3D part and then update the views to see the modifications take place on the drawing. You also were able to remove the link by isolating the view. When creating views using an assembly your views are linked to every item within that assembly by default. There are options that allow you to modify those links and to even apply those links to other views. Open the View Links document and drawing located in the View Links directory. Press the third mouse button while on the Front view and select Front view object, Modify Links. The Link Modification window appears. By default the view is pointed to the whole assembly.

2D Geometry Besides generating geometry from a 3D part or product, you can also create 2D geometry manually. This geometry is commonly used for defining elements that aid in dimensioning and to build title blocks. Of course once your company has defined their title blocks you do not need to create your own. You also have the option of creating 2D views without having a 3D part or product. This is usually referred to as interactive drafting. Creating a view When you are going to create your own views without using a 3D part or product you need to create a view that the geometry will exist in. This is easily done. Start a new drawing with an empty sheet, the settings should be ASME Standard, C ANSI Sheet Style, Landscape orientation. Select the new view icon.

You need to specify a location.

Select in the lower left corner of the sheet. A new view is created with no geometry. Drawing tools The drawing tools are identical to your sketcher tools. They are reorganized a little differently but you have the same options. One exception is that you only have a constraint by dialog icon. You do not have the constraint icon. This is okay because you use dimensions to constrain your geometry. You do need to change the dimensions to be driving dimensions. Select the profile icon. Create the following profile. Notice that no constraints were generated as you created this profile.

You have two options in the bottom toolbar which allow you to have detected constraints created and shown. Make sure the show constraints icon is highlighted. constraints. Turn on the create detected constraints icon. as you create geometry.

This will allow you to see the

This will create detected constraints

Select the undo icon until the profile disappears. You are going to create the profile again with the create detected constraints icon on. Create the profile again. You should see little blue h and v constraints appear on your lines. Make sure you have the axis visualization turned on under Tools, Options.

Select the geometrical constraint icon. Select the vertical axis and the leftmost vertical line of your profile and then select in space. The line turns green because it is constrained with a coincidence constraint is created. Select the geometrical constraint icon and select horizontal axis and the bottom horizontal line and select in space. The line turns green because it is constrained with a coincidence constraint.

This icon is used the same way you used it earlier to

Make sure you are numeric standard is set to NUM.DINC. Select the bottom horizontal line and the top left horizontal line and position the dimension. A dimension appears. Notice the top line did not turn green because this is just a dimension not a constraint. You need to make this dimension a driving dimension in order to make it act like a constraint. Double select on the dimension with the first mouse button. A Dimension Value window appears.

Select the Drive geometry option and change the value to be 4.5 and select OK. If you select off the dimension you will notice that it is a blue color representing a driving dimension. The top left horizontal line is constrained. Since you are going to be creating a lot of these driving dimensions you will want to set it up so they are created on the fly. Go to pull down menu Tools, Options, Mechanical Design, Drafting, Dimension and turn on the Create driving dimension option and select OK. This will set it up so that when you create a dimension it is automatically a driving dimension. This is normally the setting you will want to use when constraining 2D geometry. Create the remaining constraints as shown below. The top two horizontal lines have a coincidence applied between them.

Your view should be perfectly constrained. You are now ready to create the Top view. Select the new view icon and position it above the Front view. A new view is created called the Top view. Activate the Top view. Press the third mouse button while on the Front view and select Front view object, Show Folding Lines. Folding lines appear from the Front view. You will use these to create your geometry at those locations. Select the rectangle icon. It is located under the profile icon. You are going to create a rectangle by defining the two corners. Select at the origin of the view and then define the opposite corner. Make sure when you select the opposite corner the rightmost folding line is highlighted. This will make that corner lie on that line. Select the line icon. Create the two lines on the interior of the rectangle as shown below. Make sure when you select the end points of the lines that both the outside edge line and the folding line are highlighted. Put a driving dimension between the bottom and top horizontal lines and change the value to be 3.50. Press the third mouse button while on the Front view and select Front view object, Hide Folding Lines. You may need to move the view name down a little.

I know this seems like a pain and it is. CATIA is designed to be a 3D package and therefore the 2D only tools are not the best in the world. Luckily you do not need to use these options very often. You are almost done doing views manually. Create a new view and position it to the right and in between the two existing views. It is called an Isometric view. Activate the view. View plane definition Select the view plane definition icon. You can find this icon by turning on the Multi View (2.5D) toolbar using pull down menu View, Toolbars. You can also select the View Plane Definition option under the pull down menu Tools, Multi View(2.5D). The View Plane window appears.

You can play with the different options on your own. This determines the axis orientation for the new view. You can use this option on any new view to create auxiliary views or isometric views. Select the ZXY axis in the middle of the top row and select OK. This orients the view to be in an isometric orientation. You will not notice until you start projecting geometry.

Multiple view projection Select the multiple view projection icon. This can be found on the Multi View toolbar as well. You can also select the Multiple View Projection option under the pull down menu Tools, Multi View(2.5D). This will allow you to define a plane in one view and the geometry that goes on that plane in another view. The new geometry gets created in the active view. Select the top horizontal line in the Top view. This defines a plane. Select all of the lines in the Front view. You see the lines appear in the Isometric view as you select and also the lines highlight in the Front view so you know what you have already selected. Select the multiple view projection icon again. This deactivates it so you can define another plane. Select the multiple view projection icon again. Select the bottom horizontal line in the Top view. This defines a plane. Select all of the lines in the Front view. The lines appear in the Isometric view at a different location. Select the multiple view projection icon again to deactivate it. Now all you have to do is create eight lines connecting the corners. Select the multiple view projection icon again. Select one of the top horizontal lines in the Front view. This defines a plane. Select all four vertical lines in the Top view. The lines appear in the Isometric view. Select the multiple view projection icon again to deactivate it. Select the multiple view projection icon again. Select the middle horizontal line in the Front view. This defines a plane. Select the two inside vertical lines in the Top view.

CATIA® V5R14

2D Components You need to create a detail sheet and then you can define a 2D component on that sheet. When you are ready to use the component on your drawing you will use the instantiate 2D component icon. You are going to quickly define a 2D component and then use it on your drawing. You have the option of putting these components in the catalog and then being able to use them on a variety of drawings. That option will not be covered in this class. Select the new detail sheet icon. It is located under the new sheet icon. A new sheet appears in your drawing but the label has the word (Detail) on it so you can distinguish a detail sheet from a regular sheet. A view is already available to define the 2D component. Create a hexagon with a circle on the inside of the hexagon and dimensioned with driving dimensions as shown below.

Go to Sheet.1 and activate the Top view. Select the instantiate 2D component icon.

You need to specify a component.

Go to Sheet.2 (Detail) and select the component. It automatically takes you back to Sheet.1.

Position the component as shown. This time you are not going to resize it.

Go to the detail sheet and change the dimension of the inner circle to be 1.5 inches. Return to Sheet.1. Notice that the circles automatically adjusted to be bigger because they are linked to the detail. You have the option to explode the component into geometry that is not linked by using the third mouse button. You can also add a leader to the component using the third mouse button. Press the third mouse button while on the smaller component and choose the Add Leader option. Select the origin point of the view. A leader appears from the center of the component to the origin. There are times when you have many 2D Components in your drawing and you need to modify the reference component. Press the third mouse button while on the smaller component and choose Edit Reference Component. Change the diameter of the inner circle to be 1.00 and return to Sheet.1. You can also replace the reference component. Go to Sheet.2 (Detail). You are going to create another component. Select the new view icon and position it somewhere on the sheet and make it active.

Background The background option allows you to create a title block for your drawings. There are some standard scripts that come with CATIA that will automatically create a title block for you. You can also create your own script that can be executed when you need a title block. Another option that you have is to create your title block using the drawing and annotation tools that are available. There is a model with a title block that is provided that you can use for your models if you do not want to create your own. Start a new drawing with an empty sheet, the settings should be ASME Standard, D ANSI Sheet Style, Landscape orientation. Select the Background option under pull down menu Edit. You have two new icons appear that you have not seen before. Allows you to create a frame Inserts a bill of material, this is the same as inserting the bill of material in your working views Select the frame creation icon.

The Insert Frame and Title Block window appears.

Style of Titleblock

There are three styles that are available: CATDrwFrame_TitleBlock, Drawing_Titleblock_Sample1 and Drawing_Titleblock_Sample2

Action

Depending on the style you have a series of actions that you can perform to either create the title block or to modify the title block

Change the style to be Drawing_Titleblock_Sample2 and choose the Action Creation and select Apply. Notice that the title block gets generated to fit on the current sheet.

Select OK. Around the outside of the title block there are letters and numbers to create sections on the sheet and then in the lower right corner there is an information block as shown below.

You can modify this title block by changing the text or creating additional geometry. There are some other actions that were available with this title block that you can execute as well. All of this is tied to the script that was created and provided by CATIA. Your company will probably develop their own script to create title blocks that fit different size sheets. For your own experience you are going to use some of the actions provided by CATIA and then you are going to start over and create your own title block from scratch. Select the frame creation icon again. Choose the Action CheckedBy and select Apply. A window appears allowing you to enter the name of the person who checked this drawing. Key in your name and select OK. The name automatically appears in the title block under the CHECKED BY section. Choose the Action AddRevisionBlock and select Apply. A window appears allowing you to specify the initials of the reviewer. Key in your initials and select OK. A window appears allowing you to key in comments. Key in Empty Drawing and select OK. Select OK. This will exit the Insert Frame and Title Block window. In the upper right corner of the sheet you will see a revision block that was added to your title block.

If you were to choose the AddRevisionBlock action again it will add an additional line to this block. You can see how easy it is to work with the title block if it is set up by your company using a script. You will now explore creating a title block from scratch.

Review You can choose how much review you would like to do. If you want to start at the very beginning you can start with the GDT part and create the views and then dimension, annotate and markup the views as necessary. If you want to start with the views already created then you can use the GDT drawing and then dimension, annotate and markup the views as necessary. If you want to begin with most of the dimensions done then you can use the GDTfinished drawing. If you want to begin where you left off with the part earlier in the class then you can start with the GDTfinished2 drawing. The exercise will show you the steps if you start with the GDTfinished2 drawing. If you begin earlier then you need to create the necessary views or dimensions as shown in each diagram.

Geometry in all viewpoints Using this review problem, you will look at two final icons. The first is an analysis tool that lets you see geometry in all viewpoints. Select the show geometry in all viewpoints icon. This icon can be found by turning the Analyze option on under the pull down menu View, Toolbars. A 3D Viewer window appears, showing you the current view. Make sure the Animate option is on. Move the cursor on top of the large circle in the Front view. It highlights in blue and you can see the element highlight in the other views as well. This is a great tool to use when you are trying to see where an element exists in all the views. Move the cursor around to other views and other elements. Close the window when done. You can do this by selecting the X in the upper right corner. Filter generated elements The second icon is the filter generated elements icon. This will dim all the elements that have been generated from 3D. This is a quick method to check what has been manually created. Select the filter generated elements icon. It is located in the Tools toolbar. This dims all the geometry that has been generated from 3D. Notice that the circle and line that you created in the Front view are not dimmed as well as the title block and the dimensions. Select the filter generated elements icon again. This turns the filter off. Exporting You can easily export a drawing into different formats by changing the type when you save your document. Go to Save As under pull down menu File. In the Save as type area you can select the arrow to specify what file type you want the drawing saved in. Change the type to pdf and the name to draw.pdf and select Save. This creates a pdf file that can be put on a web site. Save the drawing again using the type tif and change the name to draw.tif. This creates a tif file that can be used with a word processor, like Microsoft Word. Close all documents. You do not need to save this drawing since you saved it earlier.

Mechanical Design - Drafting - Dimension

Dimension Creation

Specifies if you want the dimensions to follow the mouse when you are creating them. You can also specify if you want a constant offset between the dimension line and the geometry and whether or not you are creating driving dimensions. The Detect chamfer option is used to have it automatically determine the reference surfaces for a chamfer dimension.

Move

Allows you to snap when moving a dimension and you can specify that you only want to move a portion of a dimension

Line-Up

Defines the line-up defaults when performing that operation
