slant holes in mesh

[Anonymous]

hello,

i've just started to use archicad recently, so my question may sound stupid, but i really can't get any solution to this problem: how do i create those zygomorphic holes in the building draft shown in the pdf below?
i've tried to create library object from mesh, manipulating ridges, mesh points, seo (subtraction only lasts as long as the operator element is still there..), rotating vertically etc. just didn't work.
is it possible that there's no simple way to accomplish that? i'm not familiar with the gdl yet.
thanks for any help

To get a mesh with a profiled base you need another mesh with the required profile and subtract from the underside of the "final" mesh
