Hi! I'm using Archicad 14 Student on OSX. I was working on my project, and suddenly most of the library the objects became outlined with a dashed line.
Any idea what happened?
You seem to have turned on a Model View Option that has "Show Minimal Spaces" checked. In v13, that is only for furniture but your doors seem to have it too so maybe that's something new in v14.
Go to Document > Set Model View > Model View Options or, if you have the quick palette open, change the model view there itself.
