This thread is reading my mind. Just downloaded Rhino 6 so I could use grasshopper and paneling tools and i was wondering WTF when I tried to open R6 files in MOI. This saved me alot of anguish, THANK YOU.

Incidentally, as I'm relearning Rhino I am reminded how elegant and well thought the MOI experience is. The Rhino tutorials literally brag about how many different ways commands can be executed while I just shake my head at how much the unnecessarily bloated interface offends me. LOL.

Thank you Michael. Really, I appreciate everything you've done with MOI

Thanks.. told my client to send me step instead of Rhino 6.0 files.. however it didn't went well and I had to upgrade Rhino.
I fully understand, I really hate the Rhino format sometimes, or what Rhino does there. If only they switch to step file format only :-)

I'll put in a warning message if you try to open a Rhino v6 file, that way it won't be as mysterious.
