Help for EdgeSrf includes the misleading directive:
- For a surface from closed planar curves, use the PlanarSrf command.
This directive can be misleading. If an untrimmed surface is needed then EdgeSrf should be used, not PlanarSrf which will (almost always) result in a trimmed surface. In general untrimmed surfaces are preferable to trimmed surfaces.
If the input curves meet the requirements for both PlanarSrf and EdgeSrf then the only advantage to using PlanarSrf is the result will be “lighter”. This advantage needs to be weighed against the disadvantages of a trimmed surface compared to an untrimmed surface.
Help for EdgeSrf should be revised to:
For a surface from closed planar curves, the PlanarSrf command may be used if a trimmed surface is acceptable.
