5 Tech 106: 3-D Solid Modeling and Constraints Last Week • Switched mode to focus on ideas, tools, and design issues related to the course project, the AMT (Animated Mechanical Toy). • In the first phase, the objective was to translate your design ideas into sketches : – Mechanical Box, Figure, etc. Idea Sketch

6 Tech 106: 3-D Solid Modeling and Constraints What’s next? • Two weeks of digital modeling ; this week and next. – Modeling parts; then the “whole”, by assembling the parts, using constraints to perform this process. • The week after deals with building the physical model/object. Digital Model Physical Object

7 Tech 106: 3-D Solid Modeling and Constraints Motivation • Everything you’ve done so far has had the real 3D model in your head. – Remember that what you put on paper (sketches, etc.) is only 2D. It had to be, right? –P aper is 2D. • There was NO underlying 3D representation of the real object.

8 Tech 106: 3-D Solid Modeling and Constraints Solid Modeling? •A true 3-D representation of objects. Typically constructed much like you would the physical object. • 3-D Modelers, such as SolidWorks , create 3-D computer-based models of 3-D objects. – Integrating computers into the design process (3-D CAD; available since early 1980s).
