Modeling Tools

Create and manipulate SolidWorks parts, assemblies, and drawings. These are the foundational tools for any CAD workflow — opening files, creating features (extrude, revolve), and querying/setting driven dimensions.

Prerequisite: An active SolidWorks session. Most feature tools require an open Part document.
