I have an assembly with a small tab that is constrained to a rectangular cutout in a channel. There are several rectangular cutouts in the channel and I would like to pattern the tab using the cutouts. The cutouts are not evenly spaced and as far as I know, ST9 won't pattern using cutouts. Fortunately, I have hole features that are on the same channel that follow the same spacing. I was able to use the holes to "trick" SE and pattern the tabs. What are the prospects of ST10 being able to pattern on other features besides holes?
