I doubt that anyone can help with this, because it's simply too vague. But I've learned never to underestimate the R'ositeers, so here goes. I bought a set of internal anatomy models from 3-d-models.com, because it includes the detailed brain models I've been seeking. The package came as one HUGE 3DS file, with several skeletons, several organs, two brains, etc, all mounted on the same axis. (Incidentally, this seems like a poor way to wrap unrelated things together; are there no WinZips? Are there no RARs?) So I tried using Anim8or to strip out the parts I needed. This worked beautifully for some of the parts; Poser takes in the segments as good 3DS objects. But it fails for the one brain model I really want; Poser gives "error in FF3ds.arp". Does this strike a familiar note with anyone, or should I just keep fiddling? Is there some utility that specializes in pulling out pieces of a 3DS?

Maybe try a file converter and change it to OBJ format? I think Crossroads is still free.

You could use Crossroads (it's still free), but perhaps instead you can export the item from Anim8tor in another format? (.dxf/AutoCAD format is universal, and although it has an ugly habit of reversing the occasional normal, it works best for me.) /P

Crossroads did the job. Poser likes the .OBJ version of the .3DS that it couldn't digest.
