Face Curves

You can extract iso-parametric (UV) curves from a face or surface. Applications of this functionality include extracting the curves for imported surfaces and then performing localized cleanup using the face curves.

You can specify a mesh of evenly spaced curves or a position that creates two orthogonal curves.

Each curve created by this process becomes a separate 3D sketch. However, if you are editing a 3D sketch when you invoke the Face Curves tool, all extracted curves are added to the active 3D sketch.
