Open Web Joist

[Anonymous]

I'm modeling my floor joist, but there isn't a wooden open web joist available in the ArchiCAD Library, and I'm not getting much luck finding it elsewhere. I created a truss myself that resembles an open web joist, and it works... but it's extremely inconvenient when I want to stretch it longer or make other changes to it's length, because then I have to re-draw it in the section view. Besides, it doesn't even have the 'X' marks that represent the studs on it.

So I was wondering if there was somewhere I haven't looked, you guys know a good external source of GDL objects? I found none that have what I need so far.

Thanks for the help.
