One of the advantages of using Revit is in making documents. Revit makes it easy for me to create plans, elevations, legends or schedules. But some of elements in Revit models are quite tricky to make it's documents.
Curtain Wall is one of them. It's harder especially when it has curved location line. In Autocad environments, I've naturally drawn a planar for it's documents, but in Revit, I had to use 3d views, assembly or other ways to explain it through documents.
I know there are several Dynamo solutions for unfolding. But I couldn't find a great one for creating construction documents from any of them. So, I created my own dyn for the job.
1. Approach
From a selected Curtain Wall , you can get Panels or Mullions.
