I get the impression that Poser's standard scale of object and people size is 2500 millimeters = one size unit = approximately 100 inches (in v lines on .OBJ files). Is this correct? I discovered this when I made my APS underwater rifle model. The pictures were straight along the x-axis, and the article gave overall size; I blew up the pictures & rotated them until y and z were along the screen axes and i real millimeter = one pixel. Then I looked at the picture with Windows Paintbrush (which I had saved from my old Windows 3.1.1) with "see the cursor coordinate" switched on. After I finished that, I wrote a Gnu C++ program to copy the .OBJ file but divide all the v line coordinates by 2500.

I agree that 100 inches is the correct amount. One measuring ruler in freestuff, however, claim it to be 8 feet. That's 96 inches. Not a big difference, though.
