"<p>x3d_step_assy macro converts assembly CAD model to X3D. It tries to recognize "

First thing the program does is it scans all the STEP models under the "

"volume, surface area, center of mass, gyration radii and axes, as well as "
"per-color centers. Normally each part should contain just one solid, but if "
"there are more than one only the largest (by volume) will be used for "
"identification in the assembly (in that case assembly may show multiple not "
"matched solids that will still be correctly rendered in the final model with "
