Digital Jeweler, www.DigitalJeweler.NET makes use of vrml files for viewing
which are created on the fly as well as the engineering model and .stl file.
The VRML files, however, are made up of separate parts of the whole assembly
so reverse engineering(I hope) is difficult if not impossible.

Your beliefs notwithstanding, version 3.0 can.

Back here in real life, a VRML file contains exactly the same
information as the corresponding STL file. No effort is required to
"extract" it: one opens the file, then saves it as STL.

VRML may also contain many additional rendering parameters beyond what
is found in an STL file: viewpoints, grouping, color, surface
properties, textures.

I did so twice last week, with permission of course.
