Konrad,

Thanks for the update, and apologies on the delay responding.  GCI has had most of us quite busy!  Have you been able to make any more progress on VRML import?  If you can write triangle vertices to a file, you probably have enough to create BRL-CAD entities.  That’s basically all the STL importer does.

Cheers!
