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.
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,
FeatureManager Design Tree Main Menu Standard Toolbar Standard Views Toolbar View Toolbar CommandManager Status Toolbar
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.
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.
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.)
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.
• 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 Æ Options Æ Document Properties Æ Units Æ MMGS (millimeter, gram, second)
Example: Set Dimensioning Standard
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)
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
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.
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.
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:

A chemical is applied to the inside of the socket, and the pipe is then forced into the socket. The solvent softens the plastic, and when the solvent dries, a strong, permanent joint is created. The sockets are tapered slightly to allow for a tight fit with the pipe.
Module 4: Additional Part Modeling
This module provides a comprehensive understanding on additional modeling techniques such as:
Revolved, Patterning, Swept, Lofted, Rib and Shell features in SolidWorks. Below are examples of products that applied these types of features.
Revolved features
Revolved Boss/Base – material added by rotating the profiles about a centerline Revolved Cut – material removed by rotating the sketch
The Revolve parameters box provides the ability to select:
Centerline
One of the lines is collinear with the centerline to make a solid cylinder
Allow a small gap between rectangle and the centerline to create a hollow cylinder
Axis of Revolution Revolve Type • One-Direction • Mid-Plane • Two-Direction Angle
It controls the revolve thickness

12. The hole will be copied around the face by using Circular Pattern. Click View – Temporary Axes. The axis will be used as axis of rotation.
13. Select Circular Pattern from Features toolbar. Number of holes are 6.
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 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 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 pattern Fill a defined region with a pattern of features or a predefined cut shape. Typical uses include:
• Weight reduction • Ventilation holes Sketch points or Table coordinates to create the pattern
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.

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.
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.
From assemblies, you can:
1. Perform mass properties calculations on entire assemblies and also interference (clashes) detection between parts in assembly,
Assembly toolbars
Basic assembly mates
• Coincident – place two flat surfaces in the same plane
• Parallel – define two flat surfaces as parallel • Perpendicular – define two lines or planes as perpendicular to one another
• Tangent – define a cylindrical feature as tangent to a line or plane

Elements of an Assembly Drawing
¾ All parts are shown in one drawing• assembled view • sectioned assembly • exploded assembly
¾ Parts list or bill of materials (BOMs)
• Part ID, quantity, description, catalogue number, etc. ¾ Balloons
• each part is identified by a numbered balloon, and referenced to the parts list
¾ Machining and assembly instructions
