Functionality for patterning Coordinate Systems (linear, circular, sketch driven, curve driven, pattern driven pattern)
The mating between coordinate systems is very powerful (1 mate replaces 3 standard mates).
Moreover, using coordinate systems in mate references, is quick and extremely easy.
That being said, creating coordinate systems is a time consuming process. If I could pattern coordinate systems (especially as a sketch driven or pattern driven pattern), I can create a lot of "anchors" for mate references in a fraction of the time that I spend right now.
The time savings would be absolutely outstanding - 90-99%!!!
