Hi Henning-

The BIM software I used in 1994 which was useless was Softplan.  Googling
it, I see it is still around.  I have no idea how well it works now.

Revit is the direction our office is moving toward.  GSA and other clients
have spurred us in this direction.  Our first project using Revit was
design/build, a computer research facility, so we could absorb (to a
degree) the learning curve, as our construction arm would be using the BIM
model we produced.

My GSA projects are still in Autocad, but they will require BIM for future

The BIM coordinator is in my area of the office.  There is always someone
at his desk arguing about what "family" a component should belong to.
