Very good indeed, ron. I'm saving this thread. It's pretty much a tutorial in itself. As you know I'm working on a room pack, and when this subject came up a few months ago, I already had everything built. I had been using my own method of scale/import, which is an odd system, but does work, although I wouldn't claim it's anywhere near as precise as this. Mine's more of an 'eyeball' system. Anyway, I was using Max Units and basing the object size on the fact that a poser figure is 100%. Therefore, if my door was built at 110 units high, I would import it at 110%, and all the other parts of the door would be imported at the same percentage as their max unit size. This allowed me to import as 3DS and make sure everything fitted when I had to assemble 20 or 30 parts for a figure. As I say, it's not a very sophisticated system. LOL. But I wasn't dealing with figures that required an extreme degree of precision. For my next project, I'll use your way. mac
