I've been doing a lot of patterning recently and have noticed a few added extras that would be very useful:
1. Circular pattern in 2 directions - needed when setting out parts from a central datum
2. Combined linear and circular pattern - move object along a linear path and twist around an axis at the same time - needed when simulating robot stacking of orientated parts from a moulding machine (and for part design to enhance the stacking). Currently there is no way (I know) of doing this apart from manually setting up mates and linking mate dimensions - very very tedious.
