Helix Sweep

The problem in my file is, that I can't use actual FC-versions, but only the older 32bit CurvesWB.
For Mixed_Curve you need a sketch with the radius to project on and an orthogonal sketch with the profile.
Both are combined to a "rounded" profile cut.
When combining the two sketches, do it by marking always in the same sequence (or Loft is twisted!).
Rest is done by adapting Mixed_Curve-profiles angle to Helix and positioning them via y-placement at your will.

Thanks Hammax.
