Hey,
I'm using Revit 2013 to create curtain walls around my project.
For some reason - sometimes Revit doesn't join the horizontal Mullions of the walls automatically as it should at the corners. We can't find a pattern of when it will join them and when it won't - all the curtain walls are from the same type.
We've aligned all the horizntal gridlines and trimmed the curtain walls so the reference planes meet at the exact same point.
All joining is allowed. We've opened up a new project and copied the group containing the curtain walls to it and then Revit joined everything as it should.
Why does Revit not joining these Mullions?
Thanks,
David
