This has been requested before in the discussion groups, but I think it needs revisiting as it has huge time saving potential. I often get instances of a pattern where a hole pattern is interupted somewhere with an odd spacing, then continues again with the first spacing, for instance:
3 sets of holes at 150 mm spacing
2 sets of holes at 175 mm spacing
6 sets of holes at 150 mm spacing
The holes are all the same specs, and are all linear, but just need to adjust the spacing in the middle. Looking at the model I am wotking on now, I could use this functionality all over the place including things that I normally would have to fully model such as a set of four gusset plates that each have their own spacing. I would prefer to pattern them and control them via iLogic.
The same goes for circular pattern, allow both to have multiple pattern steps!
