Boolean with Curves (2)

[tonny]

Hi,

I have a curve that I imported from photoshop from the path I drew around a picture. Now I want to use that curve to create a shape so I can subtract that shape from a simple cube. I want that cuve to basically create a window of that shape into that cube. First I lofted the curve to a duplicate, then planared them. I tried using nurbs boolean subtract tool but I keep getting an error that reads:

Error: explodeNurbsShell10 (Explode Nurbs Shell Node): Not a valid NURBS shell.

How can I accomplish this task?

Thanks

Create another curve ( either in ps or maya ) which will define the frame.
Select both curves and do a bevel plus with caps turned on.

You can't boolean nurbs geometry with poly geometry.
