Project the curve onto the surface of the plane and trim the center of the circle. A somewhat late response. I've been away for a couple of days. Imhotep, I wasn't really sure what you were doing here, but after a bit playing around, I figured it out. With this, you might just not convert to a polygon mesh after all. Your other solution to create polygons with holes is a nice quick and dirty one. Like it :tup: Azimuth suggested the boolean solution (most straight forward solution). Although I try my best to avoid booleans as much as possible due to their unstable behavior (not only in Maya). Thanks for the tips. I put together some screenshots as a tiny tutorial for those whom might stumble on this thread with a similar question: Nurbs, Live & Trim 1 create NURBS model 2 select face to and Modify > Make Live 3 draw a curve on the Live surface 4 Edit Curves > Open/Close Curves to close the curve (don't know if it's required, but it's a good practice) 5 un-Live the face 6 Use Edit Nurbs > Trim Tool on the face (dotted area will be deleted) 7 a hole in your face (still rough looking) 8 increase Patches U and Patches V in you input history of the NURBS model to make the hole smooth. 9 ready to convert to polygon (if still desired so) Polygon mesh & Append 1 polygon mesh model 2 delete a face 3 Polygons > Append to Polygon Tool and click an open-faced edge. 4 Click the opposite edge to create a 4 sided polygon (click adjacent edge to create triangular polygon) 5 [Ctrl]+left_mouse_click to place the first vertex of the hole. Click following vertices without [Ctrl] button 6 Press [Enter] .. Done.
