Jonathan Chertok,
I'm not sure where you are located and the resources available locally
can be quite limiting, but here's a good case study to get a general
feel.
For large projects, the components can be shipped...I know of a project
here
in Philadelphia which is using the company below to fabricate a curtain
wall
system.
One well known company has worked on high-profile examples of this:
the Permasteelisa company, (http://www.permasteelisa.com.sg/)
for Gehry's Guggenheim, where the titanium panels were fabricated
in Italy from a CATIA model (captured from physical models). The steel
skeleton of the building was created through finite element analysis
of the CATIA mesh model, though I'm not sure who fabricated the members.
Permasteelisa has preeminence in this area, having worked on many
high-profile projects, like the Sidney opera house. It is useful to note
that
the structural engineer for many of these projects is the venerable
Ove Arup & Partners (http://www.arup.com/) who also have considerable
expertise in the working methods you're enquiring about.

Subject: ARCHITECTURAL_stl file coordinates to full scale building
List,
Bathsheba's posting has got me thinking about some earlier work of mine.
Does anyone know of detailed information that I might find with respect
to
gettting a 3D stl file (or CAD File) into large scale structural steel.
Are
there steel manufacturers or fabricators who can use a 3D wireframe with
which to semi-automate a steel structure fabrication?
If so, what do they need for the front end file information (a list of
3D
Coordinates?), and how does the manufacturing process work.
If anyone out there has, "been there done that", I'd like to understand
how
one might go from a 3D wireframe of a building to a semi-automated steel
fabrication shop. I'd particularly like to be referred to a technical
person
in a state-of-the-art structural steel fabrication plant.
Any ideas on where to start?
Jonathan Chertok
