Custom windows; how to make the hole angled?

[Anonymous]

Hey there, I have a rather urgent question. I'm working on a school assignment, using the ArchiCAD 16 Student version.

I have finally figured out how to make my own custom window for a historic church building, but it seems like the only way to make a window hole is creating a slab and labelling it "WALLHOLE"? So far so good, I have punched a hole through the wall with arched top and everything, awesome. BUT how on earth do I make the sill angled to 15 degrees as it is supposed to be? 😕 I am currently stuck with 90 degrees on all sides - is there a fix? Please tell me there is an easy way around this -.-
I am sort of panicking, thinking about making some morphs in my main model, subtracting them from the wall and hiding them in a hidden layer.

Thanks Roberto,
I had a hunch that would be the case seeing as it doesn't matter how thick the slab for the wallhole is.
It would be nice though - maybe GS is listening.

Thank you so much for all your help, guys, it is really appreciated. However, I feel like this tool could really need some tweaking from Graphisoft's side. If there is something it isn't, then it is intuitive.

Am I pushing my luck if I ask if there is a way to shape the entire niche and make it angled..? I tried by altering the other numbers for direction in the GDL 3d thing, but it didn't turn out pretty.. I miss a sweep command

I just learned that you can use roofs in modeling the window, if you give them the id "WALLNICHE" they will remain angled instead of just punching a hole in the wall at the projected outline.

Thanks to Roberto I've realised that: first — we could use more than one wallhole inside window and second — this wallhole could be angled. Important news to me
Unfortunately Wallniche for roofs doesn't work for me.
