Where, in Poser? Yup. Try 3DS or DXF. 3DS (3D Studio) exports much more details than a generic DXF. BTW, have you fiddled with your virtual memory settings? One of the theories is that you should set VM (System and then probably at the bottom of General tab. Or possibly Performance tab. I have win2000 where it's different.) to 1.5 times the amount of RAM. So, if you have 256 MB of RAM, try setting VM to 384 MB. If you've already done something like that, try checking "Let Windows manage memory (Recommended)". There are even some cases where, if you have lotsa RAM, like gigabyte or more, people recommend you to turn off Virtual Memory completely.
