Well, you can make doors and windows in Paint Shop Pro if you make them as grayscale-to-height maps. You can then colorize those maps for the textures. Check out some of the tutorials (see the tutorials link on the sidebar) for details. DXF was originally a 2-D file format for describing architectural and engineering drawings. It was later expanded to include 3 dimensions. Your 3D Architect program may just be exporting the 2-dimensional floor plans to the DXF file - you'll have to check the documentation for that software. Bryce usually will either completely import a DXF model correctly, or it will choke and complain that it couldn't import the file at all. I've never seen it import a 3D DXF file as 2D: most likely, 3D Architect is saving the file as a 2-D floor plan. cheers --flick
