revit curtain wall mullion make continuous

[jung201019]

hello

I'm working on a curtain wall project in Revit. Currently, my vertical mullions are being split by transoms, which makes it difficult to extract accurate material takeoffs.
Is there a way to prevent mullions from breaking at every grid intersection? Using parameters to group them takes too much time for large-scale projects
I need to merge these split mullions into a single continuous member and place joints at specific locations (ex_a 10mm gap) rather than at the center of the transom.

The reason I need a joint gap is to ensure that the actual construction details are accurately reflected in the shop drawings. In Revit, I need to represent a 10mm gap between mullions rather than having them joined at the center of the transom. This is essential for both precise material takeoffs and generating shop-level detailing.

hello rosie_lucas1
I still need help. I have not been able to find a solution. OTL

You can select a row of mullions (either horizontal or vertical)

and use the "Make Continuous" option.

It will not join both ways but will allow you to choose which way you want to be continuous

Hello  leslie_smith29WFP

thank u for reply.

I work for a façade company, so a higher level of detail is required. I am testing whether the existing 2D work can be replaced with 3D work using Revit. As the need for BIM is increasingly emphasized in the construction industry, I am reviewing whether it can be applied to our workflow.

1.

I used the “Make Continuous” function to segment the transom and mullion.
When creating the schedule for quantity takeoff, I would like these segmented mullions to appear as a single mullion. Currently, I created a parameter called “grid” and am sorting them using that value.

2.

I do not want the mullions to be segmented at the transom locations. I would like to create expansion joints in the mullions at the specific locations I choose.

thank u 🙂

Duplicate your curtain wall into two curtain wall elements:

1. one for the structural/continuous part of the curtain wall mullions (ex. vertical elements)
2. the other for the panels and caps/joints.

The structural curtain wall will be modeled without the horizontal grids cutting the verticals thereby resulting in a continuous length in the nomenclature.

If it does become important to model the expansion joints in the structural part you can always add new horizontal grids and use an "empty" crossing mullion to "cut" the length. When using this, you will have to re-introduce your grid parameter to help calculate the composite length of the elements.

Hope this helps,
