Got a minute? We appreciate your feedback:
For some reason my wall is not going all the way down to concrete slab despite of being connected to the concrete slab. As you can see, the other walls are connected to the slab as wall and they are displayed correctly.
Go to Solution.
Is there something (a slab maybe) in a hidden layer that is trimming the wall?
Turn all layers on and see what is there.
I finally solved it. The wall bellow was overlaping to the floor above, so in the part that looks like insulation were two walls overlaping.
