Sloping select horizontal mullions in a curtainwall

[dbaldacchino]

I have a rectilinear curtain wall with vertical and horizontal mullions. It is intersected by a sloped roof and I need to rotate two of the horizontal mullions by about 10 degrees. Now I know you can rotate the overall vertical/horizontal grid within the instance properties of a curtain wall, but I cannot find any info. about rotating select mullions. Is this possible? How can I model this with one curtainwall? The other option I thought of is to stack two curtain walls and edit the elevation profile of both pieces to the slope I want, but I really want this to be my last resort. Any tips would be greatly appreciated.

I haven't been able to find a way to do it. I used three walls - standard grid either side then rotated grid for the central wall.

I don't know if this is much use David as I am not much of curtain wall user.

The only thing that comes to mind for me is to create a type of curtain wall that has a curtain panel with the mullions that you want. Don't know if it would be very satisfactory - its just a thought.

I agree that it seems to be the case that all mullions are to have the same slope ie. its a global type of arrangement.

I've found a solution, but it's tedious....thank goodness it's only for a limited area! I pick the curtain panel, unpin it and edit the sketch. Then I add an extrusion the size of my mullion and assign the same material....then finish sketch. So there's no way to rotate just one grid, it's all about customizing panels. Not a great workflow, but possible. In my case I didn't want to create a custom panel for this one so I'm sort of editing in-place.

Thanks for looking into it mate! I'll post some screenshots when I'm done.

I realize you have a solution, and maybe I'm misundertanding, but what about a custom profile (used on the mullions in question) that is either rotated, or has a rotation parameter?

Just my .02...

Robert, I want to rotate the grid in elevation....in the plane of the curtainwall and not rotating the mullion longitudinally. There is no control over doing this for a select gridline, but it can be done for ALL horizontal grids or ALL vertical grids or both through the instance parameters of the curtain wall.

I would be interested to see the results.

Could you please post a sketch to explain the grid you are after.

Sorry for getting back to this so late. Here's a snapshot of what I ended up with. I basically started from a regular curtainwall and as I finished laying it out, I made edits to the panels and added sloped "mullions" (solid extrusions) while editing the panels.
