SolidWorks Training (Basic)

1

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


2

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

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.

FeatureManager Design Tree

Main Menu Standard Toolbar

Standard Views Toolbar

View Toolbar

CommandManager

Status Toolbar


3

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.


4

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 features 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. 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:

Title bar

Help. Open the corresponding help topic.

OK. Accept the selections, execute the command, and close the PropertyManager.

Cancel. Ignore any selections and close the PropertyManager.

Preview. Display a preview of the feature.

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.


6

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


7

Document Properties This setting only applied to individual documents. For example, units, drafting standard, material properties, image quality etc. They are saved with the document and do not change. Example: Setting Units Tools Options Document Properties Units MMGS (millimeter, gram, second)

Example: To increase the quality of image


8

Example: Set Dimensioning Standard


9

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 Sweeps

Revolves 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)


10

Sketch Entities/Geometry SolidWorks offers a rich variety of sketch tools for creating profile geometry.

Sketch entity Toolbar button Geometry example

Line

Circle

Centerpoint Arc

3 Point Arc

Tangent Arc

Ellipse

Partial Ellipse

Parabola

Spline

Polygon

Rectangle

Parallelogram

Point

Centerline


11

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

1. Blue

Under constrained

(this is usually appears when first

drawn)

2. Black

Fully constrained

(when more constraints and dimensions are

added to the sketch the sketch

become completely defined)

3. Red

Over constrained

(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 pop-out and it will create more problems for yourself.


12

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

One or more lines or two or more points.

The lines become horizontal or vertical (as defined by the current sketch space). Points are aligned horizontally or vertically.

Collinear Two or more lines. The items lie on the same infinite line.

Coradial Two or more arcs. The items share the same centerpoint and radius.

Perpendicular Two lines. The two items are perpendicular to each other.

Parallel Two or more lines.

A line and a plane (or a planar face) in a 3D sketch.

The items are parallel to each other.

The line is parallel to the selected plane.

Tangent An arc, ellipse, or spline, and a line or arc.

The two items remain tangent.

Concentric Two or more arcs, or a point and an arc.

The arcs share the same centerpoint.

Midpoint Two lines or a point and a line.

The point remains at the midpoint of the line.

Intersection Two lines and one point.

The point remains at the intersection of the lines.

Coincident A point and a line, arc, or ellipse.

The point lies on the line, arc, or ellipse.

Equal Two or more lines or two or more arcs.

The line lengths or radii remain equal.

Symmetric A centerline and two points, lines, arcs, or ellipses.

The items remain equidistant from the centerline, on a line perpendicular to the centerline.

Fix Any entity. The entitys 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.

Merge Points Two sketch points or endpoints.

The two points are merged into a single point.


13

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:

Where to find it

Select the sketch entity or entities, and select the appropriate relation from the Add Relations section of the PropertyManager

Or, right click the entity or entities, and select Add Relation from the short-cut menu

Or, click Tools, Relations, Add Or, on the Sketch toolbar click Add Relation

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.

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

Linear pattern Select the features, then specify the direction, the linear spacing, and the total number of instances.

Circular pattern 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.

Curve driven pattern

Module 5: Assembly Modeling Stages in the process;

1. Creating a new assembly New assemblies are created using the same method as new parts

2. Adding the first component Components can be added in several ways. They can be dragged and dropped from an

open part window or opened from standard browser.

3. Position of the first component The initial component added to the assembly is automatically fixed as it is added.

Others components can be positioned after they are added.

4. Mating components to each other Mates are used to position and orient components with reference to each other. Mates

remove degrees of freedom from the components.


79

Concentric mate between two cylindrical faces

5. Sub assemblies Assemblies can be created and inserted into the current assembly. They are

considered sub-assembly components.


80

From assemblies, you can: 1. Perform mass properties calculations on entire assemblies and also interference

(clashes) detection between parts in assembly,

2. Create an exploded view of an assembly,

3. Bill of Materials (BOM) table can be generated from the assembly. Associated

balloons can be added to identify the items.


81
