PartDesign Workbench: Adding Missing Information

[Reqrefusion]

Many new features have been added to FreeCAD for PartDesign Workbench, but these haven't been included in the documentation. The relevant PRs that added these features need to be found and added to the documentation.

Please do not refer to anything else in this issue. It will be automatically deleted.
