Making Curved Mullions that Can Be Scheduled In Revit

Interesting question raised by Rene Pellicer Garcia on LinkedIn recently:
I found that I just couldn’t make real Revit curved mullions (of the right category, schedulable, measurable, etc). Best I could do was a geometry that looks very mullion-like, but can’t schedule it, measure it or quantify it…

It is one of those situations where there are many ways to accomplish the same task, and those methods could include:

  • Traditional family modelling
  • Adaptive components
  • Dynamo
  • Non-typical modelling (railings, structural framing etc)

I decided to give it a go with the Adaptive Component method. Here’s how I attacked the problem:

  1. Created an adaptive profile family
  2. Nested that into a 3 point Arc Mullion Adaptive family, and hosted it on the arc reference line
  3. In the Arc Mullion Adaptive, made the main mullion form from the profile and the arc
  4. Created a rig of Reference Lines to host the Arc Length Dimension
  5. Used some hosted points on the Arc as intersected references for the Arc Length Dimension
  6. Made a…
