I've drawn some curves and turned them into a NURBS surface. Great! Now I want to round the corners. Is there a way to do that in FormZ? I'm looking for a tool like the 2D Fillet tool. I haven't found tool like that that will work on NURBS surfaces.
Please Help!

David,

You could draw a cutting curve and Trim the surface with the arc -- or you could Thicken the surface and then Round the resulting segments...

I thought about those two methods but,
There's no way to draw precise curves to use as cutting objects and I don't what the surface to have I thickness.
Any other ideas?

Or rather I should say, there's no way to round the corners to a specified radius if I use the cutting curve method.

David,

If you Thicken and Round, you can then Derive the surface of this if you like...

OK. That worked. Thanks.
To extract the surface, Is there a better way to do it other than using the Derive Face tool and deleting the surfaces I don't need?

David,

By default only the selected face will be derived and the others will be ghosted. Are you using the Derive Faces tool on the entire object instead of just the desired face? Or do you have your Status of Operands set to Keep?
