I have done most of my 2d drawing in Rhino...and one feature I really like and use a lot is the ability to move the origin. This makes it easy to work from a known location when placing parts on a sheet. I know there are construction lines...but these don't seem to give me the same ease of use as just being able to move the 0,0 point...and then when all is said and done return it to it original spot. Is there anything like this in MOI?

I think that the C-Plane feature is what you are looking for. It's under the View menu. It allows you to align the views to a new axis. When you are done, you just re-set the C-plane and it goes back to the default origin.

Exactly what I was looking for! I use other software also and requested this and their reply was like I was crazy...this make quick layout of parts so much easier for me. Thanks.
