Hi. I am currently in the middle of creating a multi-floor project with 4 floors total. I have already drawn the basement level from provided floorplan but now I need to create ground level and other floors which all have a slightly different floorplans. But when I try to upload a new floorplan for the ground level, I only have an option to erase my whole project.
Can anyone help? Thank you!
