Hi, I am working on a three story house. The lowest level is -9', the next floor is at 0and the top (third) floor is 12'. When I place doors in the walls at the lower level they dont show up in the floor plan. My walls are not linked.

 I have no idea why these numbers dont add up to the total of 27'; they add up to 26'-11 1/2". I did not think archicad could mis calculate? In Project Preferences, my working units are set at "feet and fractional inches", my dimensions are set at 1/...

When I use the "save view and place on layout" function the drawing disappears. Please help. Operating system used: Mac Intel-based Sonoma
