Making hole in vertical slab, why is it so complicated

[cocoloco]

I know this has been posted countless times, but none of the suggested resolutions seem to work for me (MacBook user).

I’m trying to create very ***simple***  hole or cutout shape in a slab (elevation), but Archicad won’t allow it. I’ve tried both 2D and 3D approaches — first by drawing, but that produces odd, distorted shapes that are very difficult to manage (sweet Revit). I also expected to be able to “subtract from polygon,” but that option isn’t even available for vertical slabs for some reason. And adding an opening to a slab feels like a mission on its own completely ignoring measurements I set up making full hole instead of just the size I made... 

Honestly, the software’s interface really needs a major upgrade, especially considering its pricing.

This is a workaround, and it might have been suggested before but here it goes:

-Create a beam in 3d, change its shape as desired (round, rectangular, custom profile).

-Assign 'Air Space' material for its structure.

-Go into Building Materials settings, find 'Air Space'. Crank up the Intersection Priority to 999

-Position it as desired.

Sorry, what is a vertical slab? 😁

You mean.... a wall?

Hahaha you made me laugh. 😆 But no I mean actually slab (built vertically) I mean it’s a fireplace face (marble slab) so i didn’t want to call it a wall.

Personally, I would use a wall and place an empty opening window in it or use the opening tool.

Or you could use a tall skinny slab and still use the opening tool.

If you do it in 3D, you can place a horizontal opening with the opening tool.
