I've attached the part. The problem comes when I place a dimension between the two shapes (the DIM with a value of .305"). I can't think of any reason why adding this dimension would cause the sketch to become unsolvable. I created this same sketch in Solid Edge and it did it no problem. Also, you should be able to add an equal relation to the two lowest, right-hand lines of the two different patterns, but this makes it go unsolvable too. Once again, I was able to do this in Solid Edge (see image) no problem.
Any ideas, am I missing something? I've used Solid Edge for a lot longer than SW, but I feel this isn't something I'm doing wrong, just SW's solver.
First of all, it is often better/easier/quicker to pattern a feature (or body) rather than pattern in a sketch.
I don't have time to figure out exactly why that sketch doesn't work ... other than it has too many constraints.
An alternate method if you have to create multiple copies within a sketch, is to fully constrain the seed (yours isn't) and then simply copy the seed (complete with dimensions) along a vector.
