I see this quite often, and I'm wondering what other people think about it. It's when a feature was modeled at, say, 2.125, then dimensioned on a drawing as 2.13. If you want the dimension at 2.13, shouldn't you model it at 2.13? If you round just due to default tolerances, why not just keep the dimension at 2.125 and add a tolerance to it?
The issue is that your drawings are set at 2 decimals while your model is set to 3 or 4. This would be a discrepancy between the model/ assembly template and the drawing templates. This can be set in the following location.
It can also be edited per dimension here.
Select the dim, select other, and select over ride units.
