What software do you use? (CAD/BIM)

Hi everyone!

As I'm sure everyone here is well aware, over the last couple of decades CAD and BIM software like AutoCAD and Revit have steadily all but taken over a lot of the fundamental areas in architectural planning.

With that in mind, I'm going to take advantage of the very international community we have here and ask a question that has come up quite often recently:

What software solution do you use predominantly at your firm, or at your school?

Or perhaps more to the point, what, if any, software is used most often as a "standard" in your country?

Here are a few of the popular ones, just off the top of my head:

Vectorworks, All Plan

The AutoCAD family, Revit

Archicad

Bently Architecture

I'm also very curious if anyone still uses an orthodox all-paper approach, and whether it's still viable these days.

Lastly, how many of you out there routinely use Sketchup for the early stages of planning?

The reason I ask is that many of us at my school here in Tokyo are a little confused as to what tools are commonly used outside of Japan. Even here teachers can't seem to agree on whether Vectorworks or AutoCAD is dominant locally.

Looking forward to your inputs!
