Curtain Wall Custom Corner Mullion

[Archrise]

Hi all,

I'm diving into trying to recreate the curtain wall for an existing project.

I've been trying to figure out how to create custom corner mullions as the OOTB corner mullions don't seem to fit the bill. The mullion I'm trying to make should be a fairly standard curtain wall mullion. I have have both inside and outside corners of numerous odd angles all around the building.

Ideally I would try to make a mullion that adapts to any angle the CW is joined at similar to the Revit OOTB mullions, but with the correct shape.

An alternative I've seen is to build them as male and female halves with detail in a detail component, but I can't even figure out where to find corner mullions to start with.

This must have been done before. At any rate, how do I locate the base family file for the OOTB corner to look at modifying it?

a little advice from a full time curtain wall detailer: I'm sure some might disagree but I'd dump the idea of having a curtain wall corner mullion from a curtain wall mullion profile especially if you need variable angles. I spent months trying to do what you are now starting and the pain that results just ain't worth it. I use a generic model for my corners and with that method a variable angle corner mullion can be created. As I have to provide accurate glass takeoffs I handle the sizing of glazing at corner conditions with an identifying parameter for those panels at the corners then a revised sized based on a formula.

+1 for Generic Model "mullions." Then i put the CW itself on Disallow join, and drag it back so that the glass is the exact right size. It means the GM geometry overlaps with the real revit mullions a little bit, but i dont mind that.

Which is a lot easier than creating multiple "half" profiles to make it work using Revit CW elements....

One thing to also consider is to possibly make it an adaptive family. If the category is remaining Generic Model then by using an adaptive family the faces of the existing wall could be used to update the angles of the mullion. I haven't tried this for mullions but have something similar for corner guards.

This sounds basically like what I want to do. At the moment I just can't find the base material to use as a starting point. Too much of a Revit noob to figure it out from scratch. Would like to find the base corner mullion family but for some reason I can't find where it is located.

Not sure I fully understand what you're saying. At the moment I'm trying to make something that appears correct on our 1/8"=1'-0" plans. In real life they are custom male & female extrusions for each angle. The fabricator even experimented briefly with using the slop in the system to accommodate angles that were close to each other to cut down on the number of extrusions, but of course that didn't pan out.

There isn't a base corner mullion family that you can use. These are system families, I guess the programmers thought it would be too complicated to allow users to have a profile since it adjusts to all the desired angles.

if you create a generic model corner mullion that is the actual size that it should be and place it in your model if will look correct regardless of the scale of the view. Unless you are working with a unitized curtain wall system "in real life" corner mullions are normally one piece. As with all things there are exceptions. Can you post a picture of the corner mullion that you are trying to mimic and let me know why it would be required to be in two pieces in the model? If it really must be two pieces then make two mullion halves as generic models and put them together.

Seems I'm not the only one with this problem. The person on this thread (link below) is trying to model almost the same thing. Mine is 7" and no cap at the horizontal. See Image.

After hours of searching for a possible solution I'm almost convinced its not possible get where I want to go as we are locked out of system families. Seems ridiculous for this fairly typical curtain wall detail.

The closest thing I've found so far is in a Wausau component from Autodesk Seek. Only thing is when I hover over the mullions they identify as "sweep" so are they just dumb extrusion instead of proper revit mullions?

Modeling in place components for each of the angles seems like a daunting task for the number of angles on the project.
