Door reveal in multiple thickness walls

[Anonymous]

Hi,

I can't figure it out if there's a simple solution for this or not, so maybe someone can help.

There's a screenshot what i want to achieve:

I want the model to be as simple as possible, but in this situation the door don't recognize adjoining thicker walls, so I can't use reveal. And I can't use wall closure (I'm modelling building from point cloud and therefore it's detailed but wall don't have different skins to play with). And I can't change the door frame thickness.

I used polygonal geometry method to override walls, but its not good solution, because I lose wall thickness parameter and model gets too complex as I have similar, but different situations all over the project.

It's like a big issue in ArchiCAD - when you have door or window inside multiple wall connection, it doesn't connect them correctly or...?

I'm using ArchiCAD 21

Can anyone help me out?

How is this modelled?

Doors and windows can only belong to one wall.
So reveal and closure settings will only affect the wall they are in, not any adjacent walls.

If they are polygon walls you can re-shape the polygon to form vertical reveals.
Personally I would avoid polygon walls unless they are odd shapes.
So in your case here where the walls are different thicknesses, I would treat that as an odd shape.
You could create one polygon wall (for walls 1, 2 & 3) and add another wall over for the extra thickness of wall 4, allowing you to use the door reveal if you need it.
Rather than individual walls next to each other.

Or if you need to use individual walls. maybe add empty openings to them and move them to the side to overlap with your door.
This might get messy though.
I'm not sure if you have the same reveal settings for openings though as I don't use those Graphisoft objects.

Yeah that's what I thought.

(Doors and windows can only belong to one wall.
So reveal and closure settings will only affect the wall they are in, not any adjacent walls.)

It would be great if ArchiCAD figures out how to separate openings from one wall so it would be possible to move openings between multiple walls.

I think I combine 3 walls to polygonal wall and plant the door inside. It allows me to work with reveal.

If anyone have another idea or workaround then I'd be happy to hear about that.

Using wall tool and its polygonal geometry method and multiple walls.
