This presentation provides an overview of SolidWorks, a 3D mechanical CAD program. It discusses the main modules in SolidWorks including part modeling, assembly modeling, surface modeling, and drawings. For part modeling, it explains the basic modeling process of planning the part, creating the base feature, adding remaining features, and modifying as needed. It also discusses assembly modeling using mates to control part movement. The presentation demonstrates some common sketching and 3D feature commands and provides examples of their use, such as extruding, sweeping, revolving, and lofting. It concludes with a brief introduction to SolidWorks assemblies.
