What is SolidWorks? ! SolidWorks is design automation software. ! 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.
