1 Lecture 4 – Part 2 Introduction to SolidWorks IAT 106Spatial Thinking and CommunicatingSpring 2015Lecture 4 – Part 2Introduction to SolidWorks
2 SolidWorksSolidWorks 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 ModePart ModeDrawing ModeDrawing ModeAssembly 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:
10 User Interface - a New Part File SolidWorks User Interface Overview
11 Main elements of SolidWorks interface: Menu barPropertyManagerStatus barCommandManagerConfigurationManagerFeatureManager design treeTask PaneSearch AssistantToolbars
12 Standard View Commands Perspective togglePress ‘Space Bar’
13 Display Modes Or, go to View on Menu bar, then Click on Display Section ViewView selectDisplay modeOr, go to View onMenu bar, thenClick on Display
14 How do we actually build a Part? Build parts by combining featuresOk 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 sidesRelationships 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 featureRemoves material from part.Works like intelligent cut featureUsually 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 bossBoss featureAdds 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 historyIn Gothic architecture a boss is a decorative element covering a joint.“Boss” is a skeuomorphGo look skeuomorph up—it is a really important design concept!
19 Operation Features Fillet feature Chamfer feature Similar to a fillet. Fillet featuresFillet featureUsed to round off sharp edges.Can remove or add material.Outside edge (convex) removes material.Inside edge (concave adds material.Chamfer featureSimilar 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 sketchesSketched features are built from 2D sketches (profiles)Operation FeaturesDo not have sketchesApplied 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 planeSketch the 2D profileResulting base featureExtrude the sketch
