About Extracting Curves from Surfaces, Solids, and Faces
When working with surfaces you may want to create non-mesh wireframes displaying
the contours of a surface to experiment with and regenerate variations. Objects created
by this process can be lines, plines, splines, or arcs, depending on the surface,
solid, or face from which they are extracted and the command remains active until
you press Enter.
After modifying extracted curves, use the LOFT command to regenerate a surface that
passes through the extracted objects.
Use the chain option to preview and extract adjacent curves.
The direction option allows you to extract curves in the other direction. Isoline
curves are extracted in the U direction, by default.
Choose the spline points option to extract a spline that passes through all specified
points on the surface.
Extract Curves from Surfaces, Solids, and Faces of Solids. Extract lines, plines, splines, or arcs from surfaces and the faces of solids in either the U or V directions. Click to extract an isoline curve represented by the preview line. Curves are extracted in the U direction by default.surfaces you may want to create non-mesh wireframes displaying the contours of a surface to experiment with and regenerate variations.Surface tabCurves panelExtract Isolines.
