So I just tried welding an object cut in half via Wings3D, imported into poser, and exported/imported with weld identical vertices. The object was never moved in cartesian space. I compared the two by vertice count back in wings and the weld did not take properly. the original uncut cube with 26 verts and the cut and welded via export/import with 42. Peculiar as PhilC mentioned in that welds with body parts on figures take when tranforming figures into single props via export/import...
