Hi Anis ...

I don't have any revit experience but I did use AutoCad for many years, along with a bunch of plugins to improve it for architecture. They all seemed too regimented for my preferences. I originally bought Rhino to allow for some freedom in modeling and eventually gave up AutoCad as my primary tool for 3D and 2D as well.
MoI is like a streamlined Rhino. Lighter, faster and more intuitive. I now use it for most of my initial modeling but it does not have much to offer in 2D drafting. Perhaps it shouldn't as there are a lot of good drafting programs available at all levels of complexity. For my small architectural practice Rhino is fine for that purpose and works seamlessly with MoI.

From what I can see from here there is no single program that does it all.

cheers,
eric
