Custom curved curtain wall family issue

[marin.ljubanLGTKD]

Hi people,

I have an issue that I am hoping some of you more experienced users could solve. I need to build a custom curtain wall to place it on the building envelope.
The problem is that the building is curved and I need to be able to flex the vertical profiles to keep the right angle while simultaneously keeping the distance of the bullnose on the perimeter constant.

My idea was to build the family by sweeping both vertical and horizontal profiles. I did manage to use the angle property of the sweep to get my vertical profiles at a right angle, but my horizontal sweeps are created on a straight line, and therefore it seems impossible to keep the distance on the perimeter constant, since the curtain wall panels are at an angle to each other. Some options I tried:

1. Constraining the sweep path to an angled reference plane or line aligned to the angled vertical profile, but it seems that Revit doesn't allow such a function and just keeps sending the "Constrains are not satisfied" error as I try to change the angle.

2. I thought about doing a revolve with the specified radius, but I can't seem to load a profile.

Is there a way to load a profile in the revolve function, or to sweep along a curved path? Of course, feel free to suggest any other way of approaching the problem, even if that means building the entire family from scratch. Thanks!

Disclaimer: not a subject I'm familiar to.

If you're modeling a curved building envelope, I suppose you're doing it using a mass component. If so, why don't you give a try to custom adaptive panels?

I know that my fellow Expert Elite Karam Baki has a brilliant work regarding building envelope modeling and I recommend you take a look. It may give you some insight.

Hey Rodrigo, thanks for the answer!

I do need the families to be pretty detailed, so I figured the best way would be to model it as a family and then place the curtain wall along a predefined envelope path.

Post an image or a sketch on the final envelop you are trying to achieve ... your description is kinda making it sound more complicated than it should be

I need to be able to keep the constant distance between the glass and the outer perimeter (dimensions sketched in red) regardless of the angle between the panels.

You could create the curve curtain wall as a wall by face and mullions as a wall based family with opening cut (see attached), or an adaptive family with void.
