Generating Curvy Section

To make section along any curve, my algorithm is:

  1. Make CURVE (any, even Joined by couple fragments).

  2. Make cut SURFACE (by EXTRUDING curve).

  3. Use function IntersectTwoSets. As first set – select cutting surface, as second – objects to cut.

  4. After previous operation, new generated section curves are selected. Add to this selection cutting surface and Isolate them (or Move/Copy near).

  5. Make new flat surface with length and height the same as cutting surface.

  6. Use FlowAlongSrf. As base surface select cutting surface. Make sure, that Regid option is set to Yes.

As result: Your section will be made allong any curve, and then unroled on flat surface.
