Translations:Part Sweep/14/en

If "Frenet" is "true" the orientation of the profile is based on the local curvature and tangency vectors of the path. This keeps the orientation of the profile consistent when sweeping along a helix (because the curvature vector of a straight helix always points to its axis). However, when path is not a helix, the resulting shape can have strange looking twists sometimes. For more information, see Frenet Serret formulas.
