Spaces computed incorrectly

[sanzo]

Hi!
I finally managed to try FreeCAD Arch and BIM workbenches to reproduce the model of my new apartment.

I'm trying to get the room volumes and vertical areas, but if I define the spaces by selecting the walls, I got this strange result:

Is there a bug in the Space generation (the getShape/getCutVolume functions) or am I doing something wrong (see the project in the attachment)?

It appears that it uses infinite planes instead of the actual surfaces of the wall to cut the volume...

These are the FC info, I'm running it on Fedora 36.

It happens there is some discussion about this

Currently Arch Space has some limitation, you may find a few discussion with web search engine - with 'concave' shape of room, it would not work.

Alternatively, peoples need to do it manually, say, make a Draft Wire along the room edges, Part Extrude it, and then 'encapsulate' it under an Arch Space

Hope there are developers who improve and add features to Arch/BIM wb to iron out these corners

Thanks for the fast reply!
And sorry for this duplicate discussion, I must have been searching for the wrong terms (nothing useful came up in my searches).

Bummer, that's what I was trying to avoid

I'm a python developer, if I get some time I'll investigate this.

No problem, random search of 'FreeCAD forum Arch Space problem' happens to return something including my earlier discussion - Arch Space - Boundaries Behaviour, not sure if exactly some problem


Welcome to dig into the problem and submit a PR - Arch and BIM WB, developed by one of the founder of FreeCAD - Yorik, use python
