Mullion & joining curtain walls

[Anonymous]

hello,

I'm on a project and its a glass façade, I've drawn the curtain walls separately and now trying to join them up, I've stumbled across a area in the CAD drawing that I'm struggling to draw on Revit. (in the attached) 

Could some tell me how to draw this in revit by joining two curtain walls?

Thank you.

Even if the Mullion is a Corner one, you have to use a Rectangular Mullion in order to make a custom corner mullion as that from your image...

Use a Detail Item Family nested into a Mullion Profile Family- In my example I used a family  (Detail Item )from Revit database, but you can use other detail items from CAD/BIM libraries.
