How to make hole on wall?

[Anonymous]

Hi
I try to make holes as show in picture.

wall depth is 0.1m
I want to make hole 0.01m
How can I do it in ArchiCAD? I do not intent to use Grassopher

[Barry Kelly]

I have no answer for you sorry.
But I assume you are meaning to use the Grasshopper connection between Rhino and Archicad?
So I have moved your post.

Hi Barry Kelly
I do not intent to use Grasshopper. I hope to model in ArchiCAD.
Please change it back Working in Archicad section.

[Barry Kelly]

OK, it has been moved back.
You showed an image using Rhino which confused me.

What you are looking for in Archicad is to use the window tool and place a 'Niche' object.
Or if you are using Archicad 23 or 24 you can use the new opening tool to create a niche.

Hi
Thank Barry Kelly, I try Opening tool. It work good with rectangle and circle.
Can we create new profile for opening?

[Barry Kelly]

No unfortunately the opening tool is only square/rectangular and circular/elliptical.
In a future update/release we are hoping to get polygonal shaped openings, but it is not available at the moment.

I am unsure (without checking) if the window niche objects allow you to customise the shape as I don't use the default library objects.

Another option is to create a complex profile beam.
If the building material (fill) used to create it is stronger than the building materials in the wall, then it will automatically cut the wall away.
Just place the beam in a layer that can be turned off to hide the beam - it will leave the hole.

I like your idea @Barry Kelly. Does it affect to Schedule result, if I create beam to make hole?

[Dontknow]

You can make any shape of wallhole you want.
By giving a slab the 'wallhole' id and save it as a window.
With or without a frame with glas. Make a slab with a hole as frame.
You can give the frame any shape you want.
The red slab with het wallhole id makes the hole.

I made a video of it.

Nice, thank @Dontknow
Very details

The problem is that will create a hole through the entire thickness of the wall.
I am not sure if you use WALLNICHE instead of WALLHOLE as the ID will work - I have never tried it.

It is possible to edit the resulting object if you know a little GDL.

You would have to test with 2 identical walls - one with a niche and one without.
The volume and surface area should be reduced if you are scheduling the correct fields (i.e. gross, net and conditional areas/volumes will give different results).

The beams you can exclude from your schedules by giving it a special ID telling the schedule criteria to exclude that ID or you can just exclude the layer that he beams are in.
