All, I agree that it is essential to develope CAD skills in order to function as a small firm and 3D is rapidly becoming the medium for presenting ideas to clients. That said I have observed that, for may of us, ACAD light heavy or otherwise is a program that takes a certain non-intuitive mindset and is rapidly becoming obsolete. Aside from BIM functionality Revit attempts to provide a more intuitive 3D approach. It has long been in a state of development and as I percieve from having drafters use it, is lacking in good 2D functionality, is not especially compatible with flavors of ACAD in drawing exchange and less so in tools and menues. Despite these shorfalls, the conventional wisdom and the conventional training is to stick with what are percieved to be the most broadly adopted programs. By dint of being the heavy weight, Autodesk programs tend to rule in most US markets. Another 3d option that is widely learned because it is free and intuitive is Sketchup.
For those of us who are doing much of the work themselves, my experience is that the MAC/Windows Vectorworks offers a reasonably priced and highly capable program that is developing BIM, modeling, rendering capabilities, and Sketchup compatibility without loosing the excellent tool set they developed for 2D work. They also offer excellent tech support. The downside with this and other less widely used programs is that drawing exchange between programs looses 3d and graphic qualties that take extra time to resolve. This inhibits direct editing when working on a drawing done in another program. The smaller user base also means that options for hiring temporary or permanent design support is limited.
Consider this advise, but do take the time to evaluate a couple of programs before going through the pain and excitement learning any of these programs.
