I try to create a flat pattern from a excentric cone.
Inner botom R=100
Inner top R=300
Height = 400
Both centers are 200mm excentric.
Made it with lofted bend, and seems to be right but in work it doesnt fit at all.
I Think i see what the problem is, check the flat pattern from both parts and you will see
there is a difference.
The problem is the sketch from the gap one is paralell the other angled.
