I've taken free-form RDS 5.5 objects into Poser without any problem before. You've exported it as an *.obj file? You might try exporting it as a *.dxf; I think Poser can import them. (I don't have my machine with RDS and Poser in front of me now or I'd try it.) As for the vanishing faces -- is it the start of the extrusion or the end of it? Or is it one of the other sides? Could you post a pic to show us what's going on? Might help to figure it out. - Dex
