As far as I know you can use 3dS files in Poser. You need to go to file then select import from the drop down menu. You will have a copuple of options to select like import to center or floor. I don't know if you would be able to edit files but you can use them like any other poser file. As always with using a format not orginally inteneded for a particular program you may find some odd little problems. Hope this helps.
