I get that every now and then as well. I think I figured out a pattern, if not the solution: Paint Shop Pro's 'Browse' function (thumbnail browser, for those without PSP) will display certain DXF's, yet not others. I've had it read very large DXF's (like 100+ megs - MAN is that ever slow!), and anything in between. Tthe one's that PSP will read, won't open in anything, even the program that created it. Anything it won't read is just fine. Like I said, not a solution, but a good thing for PSP owners to be aware of. Now, can someone tell me why the heck a Paint program would be able to read a DXF if you couldn't edit it? I guess if it read OBJ's and allowed you to generate texture maps, that would be useful. Heck, if it could read ANY 3D format and generate a texture map for it, THAT would be cool. Newc
