I have a problem with the 3D (Archicad 25)! In only one floor of the building, there is a space between the slab and the wall where it shouldn't be.
I placed the slab in line with the first floor level with 265mm of thickness, as per attached screenshot. The wall is linked to the first floor having the height "first floor level-265mm". While on the other floors the walls and slabs are contiguous, in this particular floor they are detached.
The screen shot of the slab shows that it is part of an SEO (Solid Element Operation). Has the bottom of the slab been cut? It is also possible that there is another element on a hidden layer with a stronger Building Material Intersection Priority that is cutting either wall or slab.
You should add a Signature to your Profile (click the Profile button near the top of this page) with your Archicad version and operating system (see mine for an example) for more accurate help in this forum.
