NURBS trimming, blend surfaces I'm exploring Blender's NURBS functionality. So far, I've been able to define two curves and create a NURBS surface between them.

Does Blender support more advanced NURBS features like trimming and blend surfaces?

It's fine if the interface is still lacking. If the functionality is available at all, I'll probably want to use it.

FWIW, I'm interested in NURBS because I do a lot of mechanical modeling. Meshes work for that, but NURBS are a much cleaner way to model a lot of man-made objects.
This functionality was recently being worked on as part of GSOC 2014. You can view the results of the project here.

It has not yet been merged into master, but you can compile it yourself (the branch can be found here).
