INTRODUCTION In cad laboratory we are going to study about how to create a model of engineering objects and also how to create an assembly of modeled objects. The modeling softwares like catia, pro e, unigraphics are generally used in mechanical engineering field for the modeling. In this lab catia-v5r18 software is used to do the exercises. CATIA (Computer Aided Three-dimensional Interactive Application) is a multi-platform CAD/CAM/CAE. It is written in the C++ programming language. Commonly referred to as a 3D Product Lifecycle Management software suite, CATIA supports multiple stages of product development (CAx), from conceptualization, design (CAD), manufacturing (CAM), and engineering (CAE).CATIA can be customized via application programming interfaces (API). V4 can be adapted in the Fortran and C Programming languages under an API called CAA (Component Application Architecture). V5 can be adapted via the Visual Basic and C++ programming languages, an API called CAA2 or CAA V5 that is a component object model (COM)-like interface. Although later versions of CATIA V4 implemented NURBS, V4 principally used piecewise polynomial surfaces. 1.1 AN OVERVIEW OF CATIA DESIGN SOFTWARE 1.1.1 Optimal Sharing. Catia V6 users will get access to a unique, collaborative 3 dimensional environment that can be access by an unlimited number of people online. This allows people from across the globe to collaborate in a virtual environment. It has been designed to not only allow for online cooperation, but also makes offline sharing and designing easy to integrate as well. 1.1.2. Simplified Product Development. Creating a new product can be a long and complex process. It encompasses multiple design phases including the initial design, overall development, and manufacturing. Catia V6 decreases the complexity and length of the entire project because it integrates various stages of the development process so that they can be controlled and modified on a single platform. It does this by using an approach to systems engineering known as RFLP. This allows you to create several versions of the same product using different sets of requirements. This gives you a comprehensive look at what the final product could be. 1

1.1.3. Seamless Transitioning. Every version of the Catia design software is designed to allow for seamless integration with previous versions. This makes upgrading a simple process and can be completed without losing any of the information that has already been stored. Catia design software has found its way into more and more industries with each passing year. Traditionally, it gained notoriety through 3 main industries; however every industry that is involved in engineering has found it useful. Catia has become a leader in product development software and may be exactly what is needed to overcome the shortcomings of CAD software. 1.2 Tool Bars Many standard toolbars are used in the different modes like sketcher mode operational mode etc, In catia software. Here we discuss about the tool bars used in sketcher with some examples. 1.2.1 Sketcher Work Bench Tool Bars There are three standard tool bars found in the Sketcher Work Bench. The three tool bars are shown below. The individual tools found in each of the three tools are labeled to the right of the tool icon. Some tools have an arrow located at the bottom right of the tool icon. The arrow is an indication that there is more than one variation of that particular type of tool. The tools that have more than one option that are listed to the right of the default tool. To display the other tool options you must select and hold the left mouse button on the arrow as shown in Figure1.1. This will bring up the optional tools Select arrow Optional tools.

1.3 Specify A Working Plane

The next step is to create a 2 dimensional profile of the part. The Sketcher Work Bench is a two dimensional (planar) work area. To use the Sketcher Work Bench, you must specify which plane the profile is to be created on. Specifying, the plane can be done several different ways.

ZX plane

1.4 MODIFYING THE PROFILE USING CHAMFER

The Chamfer icon is also located in the Operations tool bar. This procedure assumes you know what a chamfer is. The steps required to create a chamfer are almost identical to creating a corner. Select the Chamfer icon. The command prompt at the bottom left hand of the screen , will prompt you with the following: “Select the first curve, or a common point”. For this exercise select line 5. The next command prompt will ask you to “Select the second curve”.

Fig 1.6 1.5 Constraint This tool allows you to create individual constraints, one at time. You have already applied a constraint and may not even know it. The Anchor icon is a constraint. The values attached to the Chamfer and Corner are constraints. To apply Dimensional Constraints complete the following steps: 1. Select the Constraint icon. 2. Select the line and/or Sketcher element to be constrained. 3. The Sketcher element will turn green (constraint symbol) along with the appropriate dimension and box with the value in it .To re-locate the constraint value, select the value box and drag the mouse to the desired location.

5

4. If the initial location of the constraint is not satisfactory re-select the dimension and drag and drop it at the new location. 5. To edit the value of the constraint double click on the value box. This will bring up the Constraint Definition pop up window shown in. This window shows the existing value forthe Sketcher element. This value can be edited by typing the newvalue over the existing value. Then select OK or hit the Enter key. The entities linked to the constraint will automatically be updated to the new value.

6. If the constraint is between two different entities, such as lines, select the first line and then the second line.CATIA V5 will constrain the distance between the two entities. The constraint value will appear near the constraint. To move the constraint value. For this lesson constrain your “L Shaped Extrusion” similar to the one shown in Figure

Fig 1.7

1.6 Practice Exercises: Now that your CATIA V5 tool box has some tools in it, put them to use on the following practice exercises. The shapes are simple and can be completed in one sketch. The dimensions represent the constraints you are to use in the Sketcher Work Bench. The first practice exercise has the suggested steps to completing the task along with some helpful hints.

6

Each subsequent practice exercise contains less suggested steps and helpful hints. By the last practice exercise you will be on your own. Using the Sketcher Work Bench and create the following profile and extrude to the dimensions shown below. When completed save as CAT Part”.

Fig 1.8 Suggested Steps: 1. Select the XY plane (the plane the profile will be sketched on).Reference Step 3 for information on selecting planes. 2. Enter the Sketcher Work Bench. Reference Step 4. 3. Sketch the profile of the part. Hint: use the Profile tool. 4. Anchor the lower left hand corner of the sketch. For anchoring a profile. 5. Constrain the profile to match the dimensions shown above. Reference Step 18 for constraining a profile. 6. Exit the Sketcher Work Bench, return to the Part Design Work Bench (the 3D environment). Reference Step 21 for exciting the Sketcher Work Bench and entering the Part Design Work Bench. 7. Once in the Part Design Work Bench extrude the profile to the dimension shown (2”). Reference Step 22 for extruding a profile. 8. Save the part as told in “Reference Step23for saving a file. 7

This part (profile) should be straightforward. This would be a good exerciseto try different methods of constraining and testing the results. Save the shape as mensioned. Exercise 2.CAT Part”.

Fig 1.9 To help make it easier to sketch this part set the grid Primary Spacing to 1and the Graduations to 4. This will put the grid lines in the Sketcher screen to a .25 inch spacing. With that spacing all you have to do is snap to the intersections of the grid to sketch the part.

This practice exercise is a little bit more challenging, lets see what you can down with it. Save this CAT Part as Exercise 3.CATPart”.

Fig 1.10

8

It is not as complicated as it looks. If your grid Graduations is set to 10 just snap to the intersections for the beginning and ending points of your lines. To set the constraint for the angles select the angled lines and the angle constraint will appear. Reference Step 19 for modifying the angle value. If the profile gets over constrained delete the Parallel constraint. Save the file as “ Exercise 3.CATPart”. This practice exercise should challenge you. For this part use radius values, not angles. Save this CAT Part as “Exercise 4.CATPart”.

Fig 1.11

This part can be done using the radius option in the profile command. Before starting, set the grid Primary Spacing to 1 and the Graduations to 4.

SKETCHING WITH THE PROFILE ICON (RADIUS OPTION) 1. Starting at the bottom left corner of the part. 2. Select the Profile icon from the right menu bar. 3. Sketch the vertical 1.50 inch line that defines the left edge of the part.

9

4. Now sketch the first arc along the top of the part. To do this hold down the left mouse button and drag it in the direction you want the arc to go then release the mouse button. The arc will appear and allow you to drag and place it where you want. Place it on the grid intersection 2 inches above the bottom of the part and a half-inch to the right. This will only create half of the arc needed, so the process will have to be repeated to sketch the other half of the arc. 5. Finish sketching the rest of the part. When you reach the inside .25 radius, 6. When the sketch is done constrain it to double check that all the dimensions match the part shown above. Make the necessary changes if needed.

This will give you more practice using the line and corner icons. Save this CAT Part as Exercise 5.CAT Part”

Fig 1.12

Use the Line or Profile icon first to sketch the profile using sharp corners (no radius). Once it is constrained to the dimensions above, go back and add in the radiuses using the Corner icon. *******
