I moved this to the 3D Applications support section (and deleted your duplicate post) as you will most likely find the answer to your problem here. I looked, and there is a tutorial for Maya you may find useful but it's not dealing with wrl.
Found this outside of shapeways. It's a little old but maybe helpful? I learned a long time ago the wisest thing I can do is be on my own side, be an advocate for myself and others like me. -Maya Angelou
