Lighten up. First of all, Inventor IS similar to VRML1, it might not be
identical, but Inventor was the basis for createing VRML, go check VRML history

 Well , some cases is better than none, and since inlines are not there in
Inventor, it won't be a problem when going from Inventor to VRML. I've done it

just a matter of hand editing a couple of lines.
