It is not inconsistent. It is simply the way Part Design paradigm works.Pintuxgu wrote: ↑Wed Mar 22, 2023 7:13 pm ...A sketch can be created directly (as a stand alone object) in the Draft workbench by the tool already mentioned.
When working in the PartDesign workbench however, a sketch must always be a sub object of a body. It does not allow you to create a sketch in the root of the document for example. This seems inconsistent to me.
A sketch created for use in a Part Design Body exposes the sketch Attachment property which references the sketch to the Origin object of the Body. A sketch created in such a way is a specific use of the sketch for a special purpose.
A sketch created outside the Body references the global coordinate system and (at least by default) has not attachment. It is a general purpose construct that can be used with Part workbench and other non-Part Design workbenches (Arch, Curves, etc.)
