Thanks everybody for the replies. That helped me a lot. I was totally confuse about how to start modeling in MOI.
Thanks Michael, it looks like a great program you are developing here.

How about my first question then:

How do I make a fillet on the sharp edge of these two surfaces???
I did go fillet, selected both surfaces or selected them and then click fillet, I enter the radius of .2 and nothing happens. I assume nothing happens because program can't produce it given parameters I entered so I'm wondering how do I go about doing that right way??

Thanks,

Slobodan
