So I did this part of a transformer so I can test sweep tool but it seem to fail at specific number of turns
I’ll put the shapr file also for you to test it out

First I thought selecting the line in the sweeping order will solve the problem, but sadly not 
We are going to investigate it!
Hello @KPeter
I made it with plain sketch projecting and 4 quarts instead of 2 halfs
Results are still faulty
Here is a video
Transformer update
The first workspace has some minor inaccuracies which make the sweep fail. It looks like the cube was misaligned before the projection.
But nevermind, one of my colleagues found it interesting and recorded a workflow that results in a successful sweep 
pl.: I quite like the challenging ideas you come up with

Try to sweep it and check both ends
I’ll try your way
I’m glad you like it 
Watching that video was a little painful. But I bet your colleague really wishes that there was a “snapping” point at the last number that was punched in (a poor man’s array helper) alteast you won’t have to type 0.638 many, many, many times…
@Yepher
I had to type 6.919 3 times
You don’t know 
yea, i was thinking more along the lines of doing it for real and not just a small part of the full piece…
Draw a profile, use the revolve tool determine the height and number of rotations, subtract to a square shape, draw a circle, use sweep tool on the edges, done!
