Specifying unilateral tolerances on CNC machined part

Engineer asked Mar 18,2025

When entering part specifications for a CNC machined part, I wanted to specify tolerances, however the options are only for bilateral (+/-) tolerances. I want to specify a positive, unilateral tolerance as indicated on my drawing. Is there a way to do this, or will I need to change the dimensions on my drawing to be a bilateral.


Example: I have 10 mm +0.01/-0

Do i need to change my drawing to 10.005 mm +0.005/-0.005 ? I would prefer not to as the target tolerance fits better with a unilateral specification.
