How to delete mullions in window family?

[jeanettephann]

Hi guys,

I have a window family. I was wondering if it was possible to delete the mullion 

to get it looking like something like this:

The below was done with curtain walls but I was wondering if this could still be done with windows too?

File attached. Thank you

Uncheck "Show Double Mullion Right".

Thank you for the reply. 

I'm trying to achieve something like this. Where the two windows share the same 150x150 mullion. I was wondering if there is a way to do this? Thanks again.

If is a window family then you need to edit the family and either delete the border frame or assign a Y/N parameter to  be able to turn it on and off in the project.  If it is a curtain wall then tab on the border mullion, unpin if it is pinned, and delete.

Play with the attached RFA.  

Check "Press Me" and uncheck "Show Double Mullion Right" and watch the magic happen.
