I created a Sweep 2 surface using one Rhino curve and two arc as rails. I substitute the arcs with other two Rhino curves in the same place of the Grasshopper arcs. actual: The surface was build up in the opposite side (as if a mirror was applied). expected: That the red surface was in the same place as the arc construction red surface was. also If I move the points of the curves (rails) the surface is not following in the correct way the shape of the curve.
I need to rotate the rhino curves.
Dear David Rutten, if is not a known bug and you need STEPS and better bug report let me know.
