Okay, I've got what seems to be an easy problem, but can't quite get it to work. I want to model a spring with both ends flat - but not cut. I guess what I'm essentially doing is saying that the spring pitch equals zero for the last turn of the spring. So, how would you approach this problem? Is it possible to do this in one feature? The helical sweep feature doesn't seem robust enough to address this, and a trajectory graph would probably go haywire at the ends.
