Changing Dimension Decimal Places

[eagriego]

My professor wants all of our dimensions to have 2 decimals places except for a few that he wants to have 3 decimal places. How do I change those few to have 3 places while everything else has 2?

Type dimstyle and look around.
I show my students how to create a Template with all the dimension styles they will need pre-set.
You can also right click on a dimension after creation and set Precision.
If you use the second method you can use the Match Properties to avoid having to individually set precisions - just set one dimension for each different precision and then Match Properties after dimensioning all the rest.
Attach your file here if you can't figure it out.

Whatever you do - don't turn in any drawing with the AutoCAD default 4 decimal places unless the feature a very tight (read expensive) tolerance. In my experience most machinist cannot even measure reliably to 4 dec (inch) or 3 dec (mm) places.
