Gaps on joining walls

[f0086]

Hi!

I want to create a plan for my house, so I choose the FreeCAD Arch module to do that. I've measured the rooms and the walls, so I can bring it in FreeCAD. First, I draw the walls for the first room and create walls from it (Align=Left, so the inner room width matches)

Next I use the "add" function to add the walls into one solid structure, but the corners are not connected.

EDIT: I've tried a different approach where the walls overlap

And if I put it into a structure, the edges are overlapping (

I think I am doing this completely wrong, so I searched for tutorials and other resources to learn the proper way to do that, but couln't find an answer for my problem. Can you tell me what I am doing wrong here?

Yes, this is a limitation of the Arch module, it still doesn't handle these intersections very well...

What you need to do, is to make sure the base lines of the walls form a single wire. There is a tool ( Arch->Utilities->Merge walls ) that takes several selected walls, and merges them into one. This will gather all the baselines of the selected walls, and create one sketch with all of them. Once that is done, the endpoints of the walls will still not be coincident, so you must edit the sketch and add a point constraint to join coincident endpoints.

Another way is to draw the baseline first, as one closed wire (either with a sketch or with the Draft Wire tool), then create a wall from it.
