Curtain Wall Frame Intersection Priority Greyed Out

Jere

or "grayed" out for our American viewers.


I'm designing a simple curtainwall system for a project and I want to change the default intersection priorities to have the transoms (horizontals) at 10 and the mullions (verticals) at 5. I'm doing this because all of the transoms are standard capped curtainwall and the mullions are SSG (butt glazed.) However, when I select the curtainwall, the options on the various frame dialogs are greyed-out and I can't adjust them. I can adjust them all individually, but this is a large system and would take awhile (plus, I assume there's a simple solution)

Any ideas?

Use the "Find & Select" command to search the frames by class.

According to the Help files (Virtual Building > Construction Elements > Curtain Wall: A System Tool > Curtain Wall Frames):
Frame Intersections
When two Frames meet in a Curtain Wall, the Frame with the higher priority will cut the other one.
Frame Priorities are predefined for each Frame class in Curtain Wall Settings.
...
These values are not editable at the level of Frame classes. The slider shows the intersection levels of the built-in Frames (left to right: Transom - 5; Mullion - 10; Boundary - 15).
However, you can change the intersection priority of any single selected Frame. In Curtain Wall Edit mode, select the Frame whose intersection priority you want to change.
So I don't think the default settings can be changed.

Possible only once the Curtain Wall is placed. These Find & Select options are available only after entering Edit mode.

Yes. I was referring to the image from Jere, where the Curtain Wall IS in editing mode, but frames are not selected. (He was complaining about doing the priority adjustment one frame at a time.)

Maybe the easiest solution would be to rotate the Curtain Wall in its vertical plane 90 degrees after placement so Mullions (Priority 10) will be horizontal and Transoms (Priority 5) will be vertical.
Then there is no need to change Frame Intersection Priority Numbers.

You can do the placement and rotation quickly in Section Viewpoint.

Thanks for all the tips. I just did the find & select and it worked fine. It's not a particularly large section of curtain wall so it didn't take much time. I was more curious to see if I was missing something obvious. It makes some sense to be able to change it system-wide however.

Very good idea, for flat CWs. However, it can't be used for curved ones.
