Hi,
I am trying to achieve a surface between 3 nurbs curves in houdini. I have tried using skin, sweep and combinations of it but doesnt seem to work the way i would want to. I achieved what I wanted in Rhino using the patch command (see attachment). Can anyone help me achieve this in houdini. Thanks.
Regards
Vignesh

Nurbs patches are square by nature. Trying to fit a surface between 6 edges (3 are the circles, the other 3 their connections to each other) requires more careful planning on how to build them. I don't know how Rhino solves this but you should try to take a look at the wireframe to see how the patches flow.
To still create this effect on a more conceptual level, you should create 1 patch between 2 different curves (or 4 when you need more control, the patch will still be square) and then use some kind of trim to carve out the desired shape. When you have this reference surface you can build new curves on top of it to create patches with a proper topology.
