I have always wondered if you should build the mullion within panel families or to have them as mullions? What are the differences and benefits for each option.
I understood that if you build mullions in as extrusion, there is then nothing recognized as mullion category in Revit file so that you loose the quantifiable value in the model. But if we arent keen to get the schedule for vendures, is there any other benefits to have mullions as mullions other than to have them build in.
Any insights?
'Mullions' built in a curtain panel won't join nicely as if they are created as mullions, especially at corners. There is no freedom to unpin selected mullions and change to a different type.
Thank you for your explaining.
However, considering the actual construction method, where panels usually come as a whole piece with mullions (non-structural) and they dont really join as nicely as they look in Revit anyways. Does that thus make more sense to build mullions within the panel families as nested shared families for purposes of scheduling?
framing that is a part of a unitized panel is not really "a whole piece". You have a panel with an applied support frame on it. I am a curtain wall detailer doing stick and unitized walls, ACM panels, terracotta and stone facades and in my 8 years of using Revit I have never built a mullion into a curtain panel like you are wanting to do. If you want to go that direction, try it out. You'll be back...
It's up to you. There are different ways to skin a cat. You will still need special panels or some visibility controls to take care of miter joints @ the corner conditions.
Yep...I have done this method when creating storefronts with casement windows or special mullions that flip the panels side to side.
You can consider create a nested curtain wall. The host (main) curtain wall is to show the main structural grid of the system, mainly the border frame and the vertical grid. The curtain panel is another curtain wall type having its own mullions (non structural) and panel.
Hello Dave,
Thanks for your suggestion. Could you please briefly explain why exactly you guys chose that way of dealing with mullions? What happens if your mullions is more than a extruded profile (has 3-D variations)?
Thank you!
Yeah. That is a brilliant idea. Well. Our model is more complicated to just do that though. our panels (or it really the mullion) alternates every other panel. And the mullion is a fin system with a perpendicular shading panel on top of it with fasteners. So it's not really a profile that you extrude (as how I understood mullions in Revit).

If the mullions are not actually extruded profiles then sure you can incorporate them in the custom panels.
