Short description of error
When walls are given a nonzero depth value, the addition of walls will cause the baseboard to be located inside the wall. If the angle of Wall 2 (or additional walls) is set to 0 degrees, the baseboard is in the proper location.
Exact steps for others to reproduce the error
Enable the Archimesh add-on in Preferences. Create a wall, then increase the wall depth to a non-zero value, I used 0.12 meters. Then, increase the number of walls to 2 or more. This causes the baseboard to be located on the inside of the wall.
