Snapping slow and inaccurate

Noticing inaccurate snapping more and more. Either it’s slow or considerably off.

Smarttrack is on… units are mm, origin close, and tolerance is 0.01 for an architectural site drawing of around 200,000 x 200,000mm

Is this snapping problems a result of me pushing the model size to its limit?

Hi - In a new file from the factory-default Large Objects - Millimeters.3dm template, I draw a rectangle around the origin with dimensions 200 000 x 200 000. I then draw a line snapping to one of the corners of this rectangle. I see no problems with snapping accuracy.

Please provide more information and preferably a file so that we get something we can try to reproduce.

Hi - I can’t tell from your answer if, when you do exactly what I did above, you are experiencing problems with snapping.
