On Land

Environment Information
At Rill Architects we run ArchiCAD on macOS. If you work at Rill, this is your stuff. If you don't, but you work in ArchiCAD, you may find something interesting. Anybody else, I don't know.

As far as I know, this option has always existed, but I've only fully internalized it recently.

Try this display option in your working plans and sections views:

Uniform Solid and friends

It causes walls in plan, and all elements in section, to display as solid fill of the pen of the fill pattern. In plan, this means that only the corner of the wall itself can be detected, not the inside drywall corner. This eliminates the problem of accidentally aligning counters, floor fills, and such to the core of a stud wall.

I have taken the liberty of changing the working views in the templates to employ this option.
