When a part is created in place, face selection can be used to create geometry using extrude.

Previously, parts were in-place activated, and inter-part copies of faces, or included sketch geometry was needed to create part features in the context of an assembly. While this workflow is still valid for situations where parametric linking between parts required, now faces can quickly be located for geometry creation with no links created. Other operations, such as Thin Wall, Thicken and boolean operations such as Union, Subtract, Intersect and Split can be used to create geometry while in the context of the assembly. Multi-body geometry can be created also.
