The profile to carry, drawn around the origin of its XY plane, which follows the path.
The points the path runs through, at least two.
OptionalcornerHow much the path's corners are rounded; 0 keeps them sharp, mitred so the solid keeps its width.
OptionalcircularHow many segments a whole turn of a rounded corner is divided into; more is rounder.
OptionalxWhere the profile's X axis points at the start of the path, turned square to it; left out, one is chosen. The profile then follows the path's turns without twisting.
A cross-section, a path and the corner settings for
crossSection.operations.sweep, which carries the cross-section along the path into a solid.
