If i take the 2 curves that I have used for the "extrude" and want make a sweep with it
that don't work in a reasonable time! In fact I don't wait more then 10 minutes so I don't know if that works or not!
Is that normal?

And a suggestion : can you add an "elapsed Timer" for a function from start of it to the finish (if exist) ?
So with it we can have an idea for the next time :)
