ok, I just tried changing the names of the window panes in the AOI program and THEN exporting it and then I plugged in the necessary changes for the window panes and wood areas. It works now, the panes are transparent.

Just like you said, the arched area had a hole in it, lol. I will fix that later according to your directions.

Thank you again!

Another question (sorry to keep you so busy)

About the depth:
When I import the window, the depth is extremely small (.0something), unlike yours, which is about 10 inches. I'm just wondering about that. I do make changes before finishing the import though.
