I have unified the user interface for Bezier and b-spline surfaces.
Based on the selection contents the CmdSurfaceBSurf::isActive method
determines which one can be created, and marks it for the activate
method.
For any sort of inappropriate selection contents, including foreign
shapes or mixture of Bezier and b-spline curves, the tool remains
disabled.
I have converted Nate's b-spline generation to use my superclass
FeatureBSurf and added it to the GUI. Other half-ready operations as
filling and cut are commented out.
Missing:
- the fill type must be queried from the user. The data panel lets it
modify, but it is not user-friendly.
- b-spline surface is generated, but it covers only a fraction of the
supporting curves. It may lie on OCC error.
Modifications for:
- let the surface workbench appear
- use only one Surface menu and toolbar instead of two separate ones
- create a Bezier surface using 2..4 Bezier curves (does not work yet)
- use enums for fill type
