Autocad's main customer base is the AEC industry, while 3D-MAX is used in video game and visual production. Solidworks, on the other hand, is used for modeling mechanically detailed structures - like you would produce in a machine shop.

Revit, on the other hand, is used for building information modeling. It's main domain is designing buildings.

Except for Revit and Autocad, which are somewhat interchangeable within their users' domain, none of these products really serve each others core userbase well. Hence, they are not really comparable. It's like saying Word is a bit like Excel since you can compose tables of numbers in each.

If you were to offer one to the core user of the other they would complain as much as if you were giving a steak for a vetenarian to cook.
