Curtain wall frame option for mullion/dividing frame not showing

brittsax — Tue, 19 Aug 2025 17:15:39 GMT

Hi I am trying to model a curtain wall frame and the frame to divide the panels is not showing. And I don't see an option for that type of frame. See attached picture. My goal is to use the curtain wall object to create a screen system for an exterior stair.

I am not sure I understand your issue well, but if I do, here is my answer:

In the "Boundary Frame Type and Geometry" panel, you can select which GDL Library Part to use for it. Currently, the "Built-in Butt-glazed Frame" type is used that does not have a part that separates the glasses because it butts agains the lower/inner surface of glasses.

Try to select another GDL Library Part by clicking that long button displaying the "Built-in Butt-glazed Frame" name, and select another from the available ones, like "Built-in Frame" or "Frame".

Thanks - I see now how to do it. I have to create a new frame and then apply that frame to the divided panels.
