OK, I think I understand … in order to form a perfect circle, you’d have to have an infinite number of segments/turn to get the same area, and the software doesn’t allow that.
So, is a round tube necessarily a better choice than a square tube (efficiency-wise) as a coil form?
As I mentioned, even the recyle yard wants about $10/ft for 12″ PVC drain pipe. With that in mind, can I build an adequate form for making reasonably accurate tests with a square form? If not, how can I estimate how many polygon sides would suffice for the area to reach close enough to the model to work as expected?
