Rhino 6.7 cannot import WRL (Virtual Reality Modeling Language) files

I tried to open, insert, import, and attach several WRL files from this (20 year old) website: http://www.georgehart.com/virtual-polyhedra/vp.html
It was complete failure. I use Rhino 6.7 commercial version (2018-07-29),

Which ones have you tried to open? I just grabbed a few random ones from the pages, and they open ok. I’m on SR8, though not sure anything has changed in the .wrl import between versions. @tim anything you can detect?

I think this is fixed in the service release candidate:
