Hey Michael,
Okay, I spent the morning doing some tests based on what you wrote above.
I have successfully imported the model into EI with no surfacing artifacts!
Nice!

You were correct in suggesting that EI was lookign for quads and traingles only.
But I had to run it through "transporter", which converts files to .fact files. I had been doing
that the whole time but, I had to deactivate all the shading and angle settings to off
in order to get a successful import.... don't know why that worked but it did.
The N-gons did not work with any combination of settings I tried.

So I certainly can start using MOI with my EI projects, but still think
direct "fact" support would be great, and would attract many EI users
to the software.

Thanks for the help Michael,
