The project is set for 3 decimal places. Points display, in model space, to 3 places. Flip over to PS and the viewport and they've been rounded to 2 places. Flip back to MS and it's now rounded to 2 decimal places.
Resetting the project variables (projects-drawing setup) will begin the process from the start. Then it all flips back to 2 places.
Any ideas? I'm about to pull out what's left of my hair.
