Curtain Wall flat in 3D, can't see mullions or frames

[Anonymous]

Hi!
Could someone please help me, I'm working on a project with a Transom-Mullion glass facade, and I used a curtain wall to make it in Archicad.

It looks alright in 2D, but in 3D it is completely flat!
I can see the lines of the frames when I'm standing still, but when I move around in "Explore" the wall has absolutely no lines along the frames, and the wall looks thin as paper, no matter how much I change the settings.

I tried copying a 3 Dimensional curtain wall from another project, but when I pasted it, it became 2D!
So I don't think the settings in the curtain wall itself is wrong, there's something wrong in the viewing settings in 3D or something.
Has anyone gotten any idea what's wrong?

You are using a model view option where the curtain wall options is set to schematic.
