<DIV>Katia, John,<BR clear=none><BR clear=none>I can see the attached two JPGs, so the pictures have been attached. Looking at them, the roof looks like a very shallow barrel vault. Since eQUEST or any other simulation program that I know of, accepts only planar surfaces, you will have to decompose the roof into a number of strips running lengthwise. Since these strips will be skinny rectangles, they can be input either with WIDTH, HEIGHT, TILT, etc., or as POLYGONs. John has details on how that's done in eQUEST.<BR clear=none><BR clear=none>Joe<BR clear=none><PRE class=yiv8209357709moz-signature>Joe Huang
