There should be better control of work features reference in Inventor. For example:
*Ability to add point with offset from plane or face. I have to add a plane to do that now. This functionality would add much more power to work points. Same thing with axis, now you can add axis only directly on plane, with no ability to offset from it
*Ability to add point on line with offset from other geamotery (maybe from other point on same line or plane)
*Table-like list of references used with ability to redefine only selected reference. For example point on three planes - I have to reselect all planes when I click redefine feature, even when I want to redefine only one refenrence plane.
Now it is only thing that comes in mind, maybe I will come up with more later.
Good example of work features reference control is in Pro/Engineer.
