Besides all the curvature analyzing tools I find it shockingly helpful to display only the control polygon of a surface. Seeing such control polygon as a mesh object, with no smoothing (i.e. a flat-shade mode), often reveals undesired curvatures and weird bulges on a surface:
(I bet you can see the offending vertices.)
…that means:
- ExtractControlPolygon,
- Isolate,
- FlatShade,
- modify the control polygon mesh to eliminate unwanted disortions,
- Unisolate,
- adjust the surface control points to match the now-modified control polygon mesh again,
- delete the control polygon mesh
It would be great if we could Tab a surface into a “ControlPolygon” mode, like we can with SubDs.
