View Full Version : Question 1 about vertical curtain wall mullions

I have some questions about vertical mullions. For clarity, I am going to post them in separate threads. I would appreciate any help.

The illustration provided is an elevation view showing 2 curtain wall entities. The one on the left has vertical mullions only. The length of the vertical mullion is equal to the height of wall. That's how I would like to keep it. However, as soon as I place any horizontal grid lines, my vertical mullions are broken in pieces. I would like to find a way to keep my vertical mullions as one element. The reason for this wish is that I want to be able to schedule the vertical mullion as one single piece as it really is, not as the sum of several pieces. I know how to add the lengths of the pieces in the schedule, but it would be a lot easier to schedule these vertical mullions if they were not broken into multiple pieces. My question is whether there is a way to prevent the vertical mullion to be broken by the horizontal grids, or a way to join the pieces back together into one single mullion.

Hint: none of the two methods that Revit provides to supposedly do this, works ("hold shift to create single mullion" nor the "grid line" method that is supposed to add a mullion to "an entire grid line", nor "join geometry")

See if the attached image helps.

If you select the mullion, you can toggle which one is broken. You can have one or the other, but not both continuous :(

Even if they are continous they appear as seperate items in the schedule if there is a horizontal grid line placed (you don't even need to place a mullion on the grid line.) I am fairly sure there is no way to control this behavior at the user level. It is an artifict of the way Revit is internally creating the curtain wall geometry.

I would be glad to see someone prove me wrong but I think this is "just one of those things."

Ah, I was not aware of the scheduling mechanism for mullions. That makes sense though since they are all individually selectable.
