    Curtain wall border Mullion - Profile to align at the centerline

    I am trying to design the border mullion of the curtain wall, in a way that its centerline alignes to the border gridline.

    For default the border mullion aligns the external face of it to the gridline,
    but I would like it to act as the internal mulluon - aligning with the centerline.

    How can I make it?

    Thanks a lot!

    Welcome to the forum kubbah.

    You've two ways:
    1. create a new mullion profile, drawn to suit the condition as you need it (take note of the advisory text notes in the template that explain how it'll behave)
    2. define an offset in our mullion definition, that moves the profile in/out of the line.

      every curtain wall guy in the world is now crying FOUL!! DON'T DO THAT!! It's bad enough that Architect's/Designers don't deal with caulking joints at curtain wall perimeters, now you want to center the jamb/head/sill on what is supposed to be the rough opening for the curtain wall. Build curtain walls like they are built in real life...IMO of course. As an aside I don't believe that this can be accomplished with standard Revit curtain wall profiles.

        Thats not true for every architect and designer, any more than its true that all of our Curtain Wall Subs are too unsophisticated to make intelligent use of the models we send them.

          TOUCHE! Sorry to have generalized. Frankly, the non modeling of caulking joint sizes is not really and issue with me as the joint width size is a complicated result of each buildings design criteria. So, Architects/Designers wouldn't really know the value until structural engineering review of the curtain walls was done anyway. I assume, unless specifically noted in the model/drawings that the rough opening size is the same as the curtain wall perimeter frame profile size. Has worked well for me so far...

            Old thread but I'm having the same challenge and either the above is not for what I'm trying to do or I'm just going about it wrong.

            I want my curtain wall profile to sit on a slab (no negative base offset) and have the bottom border mullion extend into the slab. I can get the mullion half in-half out of the ground (by tinkering with profile rotation, and placement, and mullion angle, and offset) but it pushes the bottom of my panel up (I'd like it to hug the top of the mullion). I think I get why it's doing that (something about where/how the profile crosses the Center (Front/Back) RP) but I can't seem to find a workaround.

            That's my stab at number 1 in Snowy's post. I get nowhere on the second approach.

            Thoughts? Maybe an example file to reverse engineer?

            Thanks.

              I'm not visualizing what you are trying to do with #1, can you make a picture? Regarding #2 Revit mullions (not profiles) have an offset parameter for in to out movement built in to them.
