I have created a spiral with some holes in it as part of a sculpture. It will be two layers deep, with the holes offset from layer 1 to layer 2. I am having a terrible time getting the holes to line up - I have squished, unrolled, silhouetted the surfaces and applied the curves to the second surface, offset the holes by 1". Can’t get them to be concentric from one layer to the next. Can you help? I’m happy to send you my file for review. THANKS!
