I come from a Catia background, where we do a lot of bigger scale parametric modeling. Within a part, typically models used for master geometry, I use 3D point/line elements a lot (not within a sketch). The ability to insert Axis systems in 3D space, and use those systems as reference elements is HUGE in kinematic design and layouts (e.g. move a point from axis system A to axis system B).
Both SW and from what i can tell Fusion, lack that ability and have some basic 3D feature ability would make my life SO much better.
