Self-sizing Beam

I was wondering several times about Self-Sizing components, to avoid stability problems in the Conceptual Design Phase. In Revit it is absolutelly possible. With adding many-many parameters, you can apply Code-Based sizing methods, but in my current example I just added an easy geometrical rule to my Beam.

First of all we need a good Template

To simlify this task, I edit the built-in Extrusion in the Template:

For this, please step into an Elevation View in the appearing list:

b for Width as a Type parameter and h for Heigth as an Instance parameter

The keypoint is the Formula of param h above.

Just load your Beam to the project and enjoy!
