I'm having a problem modelling the fusee illustated below and was wondering if the hive mind could suggest a way forward.
Essentially, the part is a helical spiral. I know I can model a helix and an intersecting spiral and project the intersection to a 3D sketch to get an appropriate curve - but....
This would probably be fine if it were 'just' a circular groove to be cut - but it isn't. If I try to sweep a shape more complex than a circle along a 3D curve, the shape twists in an unpredictable way.
Any suggestions?
