Modeling the Exterior Steel Structure of a Building
in ArchiCAD 10
Partner, Oppenheim Architecture and Design
At Cube, a 24 story condominium project in the
Design District in Miami Florida shown below,
we are using an exposed steel structural frame.
In Archicad 9, the exterior steel structure of
the building was generated using the add-on application,
TrussMaker. I was going to demonstrate how this
was done, but now with ArchiCAD 10, it is no longer
necessary to use this tool for this purpose. I
will show how a portion of this repeating structure
can be modeled in ArchiCAD 10.
First, set up a folder in the View Map
where the relevant views for this modeling exercise
can be accessed rapidly. Give it a descriptive
name and using the Organizer,
drop a floor plan, a study section and a perspective
view, so you can quickly move between these.
In ArchiCAD 10, the profile of a beam can be
specified before modeling it with the Beam
tool. Access the Beam Selection Settings
dialog, click on the Profile
icon, and select the profile HP Steel
Section. Draw a couple of beams in the
floor plan view; we will be moving these later
to the correct location in the plan and elevation
views. Do the same with the Column
Going to the study section view, we can see the
library part that was originally done with TrussMaker
and is now going to be replaced by elements created
directly with the Beam tool.
We can see the horizontal beam, the sloping beam,
and the column, both in the section view as well
as in the perspective view.
We will now move, mirror and copy, and stretch
the beams and columns to the desired location
in the section view as well as the plan view.
Next, we remove the TrussMaker library parts
and replace them with the new elements.
The next step is to make two more copies of the
horizontal beam and move them to their proper
location. They will now show in their corresponding
story automatically. You can see the results better
in the 3D view.
These new beams now have to be moved them to
their correct location in the plan view.
The 3D view shows that they are now placed correctly.
Select your view point and render to see the
results in a more photorealistic manner.
This basic frame can now be copied to other portions
of the building that are identical, or the process
can be repeated to create structural elements
for the other parts of the building that are similar
but not identical.
