Hi.
I have followed this tutorial:

As usual, any help or idea would be highly appreciated.
Regards,

I used it multiple times today, no problem. But, I have a compiled version of 0.20 and am using 7.6 OCCT.

SOLVED: Sweep in 2 rails out of scale and misplaced

After 2 days of hard working on this it is almost solved. The problem is in the hull sketch. I've built a combination of arcs but the sweep on 2 rails need a sketch with just a b-spline! :lol: :lol: :lol:

Use Curves workbench JoinCurve tool to make a single bspline out of the arcs and line segments in your sketch.
