I have set up to work in millimeters. I’m not sure it is associated, but my grid displays like this when the view is orthogonal. Is this another setting that needs to be addressed?
You will need to check yr clipping on view and later on a camera if you use one, ‘clip start’, set it to something smaller.
Hope that helps

Slight correction. The issue isn’t that the clipping start is too large but instead that the distance between the clipping start and end are too far apart. For example 0.000001m-100000m is far to much. Something like 0.0001m-10m would be much better.

There seems to be some layers of units and scales I don’t completely understand.
When, in Scene settings I set “Unit System”: Metric, “Length” to Millimeters, and “Unit Scale”: 0.001, what have I actually specified? If I now enter a “1” in a field is it interpreted in real units as 1mm? And, for instance, if “Clip Start” displays 0.001 mm, is clipping starting at 1um?
The length changes nothing other than how fields are displayed. So if the length is “Millimeters” it will show 2000mm. If the length is “Meters” it will show 2m. So this is just preference as to what you want to see.
The “Unit Scale” is basically just a bias that controls the size of everything in the scene. So changing the unit scale to 0.001 is pretty much the same as scaling everything in the scene by 0.001.
To be honest, if you’re working with microscopic scales, you should probably make everything “magnified”. So just convert everything that’s say 2mm to 2 meters, etc. Computers tend to not like tiny numbers.
