The Part Workbench provides a traditional constructive solid geometry (CSG) workflow. In this workflow each object is an independent solid. The Part Workbench can create them from parametrically defined sketches using tools like Extrude, Revolve, Loft, etc. In addition, basic primitive solids like Cube, Cylinder, etc. can be created as well. These objects can be combined, through Boolean operations, to create more complex solids.
The Part Workbench can also create objects that are not solids, such as faces, shells, and objects with only edges or vertices. It also provides a variety of general purpose tools for geometry manipulation, geometry validation, and making copies.
The PartDesign Workbench uses an alternative workflow for creating solids. For a detailed discussion of the Part Workbench versus the Part Design Workbench see Part and Part Design.
The Std Measure tool replaces the tools listed below. introduced in version 1.0
