a little curiosity


New member
Hi, I've got a little curiosity about pro-e vrml export: When export something from pro-e to vrml, pro-e generates 3 files, such as part_p.wrl, part_pr1.wrl and part_pr2.wrl. Only the file that pro-e named with pr1 work correctly, the p and pr2 don't work when I try to open it with a browser (I use Cortona). Does anyone know why pro-e do this?? If I delete the _p and _pr2 files the pr1 file still work, so what is the utility of the other two files?????
