thx for a reply mate, My process is - get a poly or group of polys the size of my window. -Extrude and scale down a little. -Extrude and move in a little. -Extrude and move to depth of window. -Extrude and move a little bit further back. -Extrude and scale down a little. This leaves my smooth mesh with sharp edges on a 'Rounded' window. Tried the bevel tool an a new window and I still ended with 5 sided polys on the four poly's off the corners. The bevel tool cut their corners just a little... LOL and just encountered another failing.. I'm not sure how to insert my wires in the message? "insert image" Button needs a http address. So I've attached one image. think I should just accept technology isn't my thing.
