This is the method I have settled on, at least for now, and I'm pleased with it. I've been trying to build a lean-to that is touching but not integrated with the second phase of the project. I want to be able to slide it up against for reference while leaving all my automatics on without CA integrating them as one structure. I have the lean-to floor plan referencing the main structure, and the main structure 3D model referencing the lean-to.

Getting this error as well. X16 Mac intel If I remember correctly, the first time it came back when I closed and reopened CA. Now it's gone, except in 3d ..... turns out I was on floor zero, with no footers and framing layers off.
