Greg, Thanks much! It took a bit of searching ("see background" is in the top pulldown menus), but it worked. I was hoping that I didn't have to determine viewpoints, vanishing points and such from the photograph. Your suggestion is much simpler. BTW, do you know why ACAD's DVIEW lenslength number doesn't correspond to 3DS's camera lenslengths? I use Visual Link and wrote a LISP program that creates a 3DS camera from the current DVIEW, but I had to multiply the lens length by a factor of 0.7. Why?? I'm still refining the program, and I'll be uploading it when it's done. Thanks again, Jeff Bradley
