Mullion Profiles

You can vary the shape of mullions by loading new mullion profiles into a project. Also, you can create a custom profile.

Revit provides some templates for mullion profile families. These templates reside in the following location:

%ALLUSERSPROFILE%\Autodesk\<product name and release>\Libraries\<locale and language>\Profiles\Curtain Wall
