Walls not drawing orthogonally

[Richard Morrison]

I'm not sure why this is, but I'm having a heck of time getting walls to draw exactly orthogonally. They end up with an angle of 89.97 deg., say. I'm not doing anything differently than I've done the past 19 years or so, at least I don't think so. Is there a setting, like a grid snap or a guideline, or behavior that I'm missing in the latest version? BTW, I jumped from AC17 to 19 (briefly) and have been working in AC20. What do I need to do differently?

Seems to be different on PC's, then. The last four orientations appear to be the same regardless of which file I open. If there is a saved rotated view which is opened, then this will replace one of the last four rotated orientations. A little confusing if you don't know what is going on.
