1 Lecture 4 – Part 2 Introduction to SolidWorks
IAT 106 Spatial Thinking and Communicating Spring 2015 Lecture 4 – Part 2 Introduction to SolidWorks

2 SolidWorks SolidWorks is an industrial-strength 3-D solid-model based computer-aided design (CAD) system. In SolidWorks, you sketch ideas and experiment with different designs to create 3D models. SolidWorks is used by students, designers, engineers, and other professionals to produce simple and complex parts, assemblies, and drawings.

3 The SolidWorks Model: 3 Design Environments
Part Mode Part Mode Drawing Mode Drawing Mode Assembly Mode

4 SolidWorks is ASSOCIATIVE
What’s it mean that SolidWorks is associative? Parts, drawings & assemblies all use the same database. So? Any change made in any of the modes (i.e. Part, Assembly, or Drawing modes) is automatically reflected in the other modes immediately.

5 SolidWorks is FEATURE-BASED
Feature: smallest building block that can be modified individually. Features are building blocks of the parts (shapes and operations).

6 SolidWorks is PARAMETRIC
Dimensions in the model drive the geometry of the model. Modifying the dimensions changes the model. Dimensions and relations are stored in the model.

7 Getting Started with SolidWorks
On opening SolidWorks, the SolidWorks window and Resource Task Pane are shown (details may vary depending on version)

8 Opening a New Model File
New button (toolbar): New SolidWorks Document dialog box is displayed:

9 File Types Modeling Part (*.sldprt) Assembly (*.sldasm) Drawing (*.slddrw) Templates: Part Template (*.prtdot) Assembly Template (*.asmdot) Drawing Template (*.drwdot)

10 User Interface - a New Part File
SolidWorks User Interface Overview

11 Main elements of SolidWorks interface:
Menu bar PropertyManager Status bar CommandManager ConfigurationManager FeatureManager design tree Task Pane Search Assistant Toolbars

12 Standard View Commands
Perspective toggle Press ‘Space Bar’

13 Display Modes Or, go to View on Menu bar, then Click on Display
Section View View select Display mode Or, go to View on Menu bar, then Click on Display

14 How do we actually build a Part?
Build parts by combining features Ok how do I make a feature? Build feature by drawing a 2D sketch and extruding it into the 3rd dimension: Use familiar drawing tools. The sketch does not need to be dimensionally accurate. Just needs to represent basic shape (topology) of profile: Number of sides Relationships between elements (parallel, etc.)

15 Features Features are the building blocks of parts.
Features are the shapes and operations that construct parts.

16 More Shape Features Cut feature Hole feature
Removes material from part. Created from 2D sketch. Must be attached to rest of part. Hole feature Removes material from part. Works like intelligent cut feature Usually corresponds to mfg process (eg countersink, thread, etc.)

17 Shape Features gothic boss Two boss features here! Base feature
First feature in part. Created from 2D sketch. Forms work piece to which other features are added. gothic boss Boss feature Adds material to part. Created from 2D sketch. Must be attached to rest of part. Two boss features here!

18 What is this term “boss”?
It’s medieval history In Gothic architecture a boss is a decorative element covering a joint. “Boss” is a skeuomorph Go look skeuomorph up—it is a really important design concept!

19 Operation Features Fillet feature Chamfer feature Similar to a fillet.
Fillet features Fillet feature Used to round off sharp edges. Can remove or add material. Outside edge (convex) removes material. Inside edge (concave adds material. Chamfer feature Similar to a fillet. Bevels edge rather than rounding it. Can remove or add material.

20 Feature attributes Sketched Features
Shape features have sketches, are based on sketches Sketched features are built from 2D sketches (profiles) Operation Features Do not have sketches Applied directly to work piece by selecting edges or faces

21 Constructing a Model Sketching on one of the default planes
Front, Top, and Right

22 Creating a Sketch-based Feature
Sketch Entities

23 Creating a Rectangular Box
Select a sketch plane. Sketch a 2D profile (a rectangle). Extrude the sketch perpendicular to sketch plane. Select the sketch plane Sketch the 2D profile Resulting base feature Extrude the sketch
