what the help file does not make absolutely clear is that they must be 100% vector wmf, and that is not going to be the case exporting from PSP AFAIK [I stopped at ver 9 of that program] - you can try importing the wmf into xara designer and see what you get - if it's bitmap [photo] it won't load into 3D maker you can only use it as texture on an underlying vector shape that you will have to make separately...
