SolidWorks Training (Basic)

Module 1: Introduction to SolidWorks and Basic Sketching (1 hour 50 minutes) Introduction to SolidWorks (20 minutes) SolidWorks is a mechanical design software package to build parts, assemblies, and drawings, which take advantage of the Microsoft Windows graphical user interface. In SolidWorks, a part, an assembly, and a drawing are all fully associated. Changes to the model are automatically reflected in the associated drawings and assemblies. Likewise, when you make change to the drawing and assembly, those changes will be reflected back to the model. Starting a SolidWorks

SolidWorks Training (Basic)

SolidWorks user interface & Toolbar menus The interface is native Windows interface, and such behaves in the same manner as other Windows applications.

Main Menu

Standard Views Toolbar

Standard Toolbar View Toolbar

CommandManager FeatureManager Design Tree

Status Toolbar

Menus • •

It provides access to all commands that the SolidWorks offers. When a menu item has a right pointing arrow, it means there is a sub-menu associated with the choice,

•

When a menu item is followed by a series of dots, it means that option opens a dialog box with additional choices or information.

2

SolidWorks Training (Basic)

Toolbars menus • •

Provide shortcuts enabling to quickly access the most frequently used commands. They are organized according to function and can be customized, removed and rearranged according to your preferences.

Example of a Toolbar Standard toolbar as shown below contains commonly used function as opening new or existing documents, saving documents, printing, copying and pasting objects, undo, redo, and help.

You can turn toolbars on and off using one of three methods. 1. Click Tools – Customize. On the Toolbars page, click the check boxes to select each toolbar you want to display. Clear the check boxes of the toolbars you want to hide.

2. Right click on toolbar area of the SolidWorks window. Check marks indicate which toolbars are currently visible. Clear the check marks of the toolbar you want to hide.

3. Clicking View – Toolbars displays the same list of toolbars.

SolidWorks Training (Basic)

FeatureManager Design Tree • • • •

It is located on the left side of the SolidWorks Graphic window. It displays the details chronological sequence on how all the parts, assembly and drawing are created. It allows access to do editing of the models. It consists of three default tabs: o FeatureManager design tree o PropertyManager o ConfigurationManager

The FeatureManager design tree makes it easy to: • • • • •

Select items in the model by name. Identify and change the order in which features are created. You can drag items in the FeatureManager design tree list to reorder them. This changes the order in which features are regenerated when the model is rebuilt. Display the dimensions of a feature by double-clicking the feature’s name. Rename items by slowly clicking two times on a name to select it and then entering a new name. Suppress and Unsuppress part features and assembly components.

The PropertyManager appears on the PropertyManager tab in the panel to the left of the graphics area. It opens when you select entities or commands defined in the PropertyManager. OK. Accept the selections, execute the command, and close the PropertyManager. Cancel. Ignore any selections and close the PropertyManager.

Title bar Help. Open the corresponding help topic. Preview. Display a preview of the feature.

The ConfigurationManager on the left side of the SolidWorks window is a means to create, select, and view multiple configurations of parts and assemblies in a document. The icons in the ConfigurationManager denote how the configuration was created: Manually With a design table Manually, and has an explode state With a design table, and has explode state 4

SolidWorks Training (Basic)

Keyboard shortcuts and mouse buttons Keyboard shortcuts Some menu items indicate a keyboard shortcut such as: Ctrl+O for File, Open Ctrl+S for File, Save Ctrl+Z for Undo And many more You can customize SolidWorks by creating your own shortcuts. Click Tools – Customize. Find Keyboard tab as in figure shown.

Three mouse buttons •

Left – to select objects as geometry, menus buttons, and objects in the FeatureManager design tree. To select multiple items, you must hold down the Control (Ctrl) key. To deselect object, simply click anywhere in a blank (empty) portion of the work area.

•

Right – activates a context sensitive shortcut menu. The contents of the menu is differ depending on what object the cursor is over.

•

Middle – use for dynamically rotating, panning, zooming a part or assembly. o Rotate part or assembly – Holding down the middle button and drag the mouse o Zoom all document types – Hold down the Shift key while depressing the middle button and moving the mouse. (Simply rotates the wheel of the middle mouse button for zooming in or out if your middle mouse button is a wheel.) o Pan all document types – Hold down the Ctrl key while depressing the middle button and drag the mouse.

Tools-Options The Options dialog box able you to customize the SolidWorks software based on your preferences. Level of customization: •

System Options

Every option under System Options will affect every document you open in SolidWorks session. For example, the viewport background, if you set the color to Black, it will remain as black every time you open the SolidWorks window until you change to another color. Example: Set Viewport Background to White

SolidWorks Training (Basic)

Basic 2D sketching (1 hour 30 minutes) Sketching is the act of creating 2-dimensional profile comprised of wireframe geometry. Sketches are used for all sketched feature in SolidWorks including: • Extrusions • Revolves • Sweeps • Lofts Process of completing the sketches Starting a New part (It can be created in inch, millimeter or other units)

Sketches (Collections of 2D geometry that are used to create solid features)

Sketch Entities/Geometry (Types of 2D geometry such as lines, circles and rectangles that make up the sketch)

Sketch Relations (Geometric relationships such as horizontal and vertical are applied to the sketch entities. The relations restrict the movement of the entities)

State of the sketch (Each sketch has a status that determines whether it is ready to be used or not. The state can fully-, under- or over defined)

Sketch tools (Tools can be used to modify the sketch geometry that has been created/ this often involves the trimming or extension of the entities)

Extruding the sketch (Extruding uses the 2D sketch to create a 3D solid feature)

Status of a sketch The most common color codes are: No. Color

Diagnostic

Case

Under constrained 1.

Blue

(this is usually appears when first drawn)

Fully constrained

2.

Black

(when more constraints and dimensions are added to the sketch – the sketch become completely defined)

Over constrained

3.

Red

(adding any dimension to fully defined would serve to overdefine the sketch)

Only case 1 and 2 are allowable. For case 3, you must fix the error as soon as possible before quitting the sketch mode otherwise a warning message will popout and it will create more problems for yourself.

11

SolidWorks Training (Basic)

Sketch Relations The following table describes the entities that you can select for a relation and the characteristics of the resulting relation. Relation Horizontal or Vertical

Entities to select One or more lines or two or more points.

Collinear

Two or more lines.

Coradial

Two or more arcs.

Perpendicular Two lines. Parallel

Tangent

Concentric Midpoint Intersection Coincident Equal Symmetric

Fix

Two or more lines. A line and a plane (or a planar face) in a 3D sketch. An arc, ellipse, or spline, and a line or arc. Two or more arcs, or a point and an arc. Two lines or a point and a line. Two lines and one point. A point and a line, arc, or ellipse. Two or more lines or two or more arcs. A centerline and two points, lines, arcs, or ellipses. Any entity.

Merge Points Two sketch points or endpoints.

Resulting relations The lines become horizontal or vertical (as defined by the current sketch space). Points are aligned horizontally or vertically. The items lie on the same infinite line. The items share the same centerpoint and radius. The two items are perpendicular to each other. The items are parallel to each other. The line is parallel to the selected plane. The two items remain tangent.

The arcs share the same centerpoint. The point remains at the midpoint of the line. The point remains at the intersection of the lines. The point lies on the line, arc, or ellipse. The line lengths or radii remain equal. The items remain equidistant from the centerline, on a line perpendicular to the centerline. The entity’s size and location are fixed. However, the end points of a fixed line are free to move along the infinite line that underlies it. Also, the endpoints of an arc or elliptical segment are free to move along the underlying full circle or ellipse. The two points are merged into a single point.

12

SolidWorks Training (Basic) A line may be constrained vertically or horizontally. Once the line is drawn horizontally, it will remain horizontal unless the relation is removed. The line can be repositioned and resized but must remain horizontal. For an instance:

The line is in Horizontal

The line is in vertical

The lines are in horizontal and have equal length

Where to find it •

Patterning In Module 2, you have learnt the sketch pattern such as linear and circular pattern. There are other pattern tools that are available in SolidWorks. You may find them at Insert – Pattern/Mirror. Pattern repeats the selected features in an array based on a seed feature. You can create a linear pattern, a circular pattern, a curve driven pattern, a fill pattern, or use sketch points or table coordinates to create the pattern. Linear pattern

Circular pattern

Curve driven pattern

Fill pattern

Sketch points or Table coordinates to create the pattern

Select the features, then specify the direction, the linear spacing, and the total number of instances. Select the features and an edge or axis as the center of rotation, and then specify the total number of instances and the angular spacing between instances. Select the features and an edge or sketch segment on which to pattern the feature. Then you can specify the type of curve, the curve method, and the alignment method. Fill a defined region with a pattern of features or a predefined cut shape. Typical uses include: • Weight reduction • Ventilation holes Select where to populate a seed feature by sketching points on model face, or Add or retrieve previously created X-Y coordinates to populate a seed feature on the face of the model.

But remember, the commands are only enable when you have multi body parts.
