I use rotated sweeps as basis to draw electrical coils. This works best on lines or arcs and not good on splines.
The basis curve is done by a formular. So I get points and normaly I would draw a spline along, but in this case it is better to draw arcs along. Then I do this rotated sweeps along the arcs.
But there is a problem: Each surface has its own profile and they do not connect.
To connect them to one surface I want to use the end-edge of an arc-sweep as profile for the next arc-sweep.
In my script you see out comanded lines where I try this. But Fusion does not accept the edge as a profile.
Does someone know a solution?
