Hi, I would like to program automatic tolerancing into my templates so that the symmetrical tolerance is applied automatically upon inserting the dimensions.

What is the Solidworks dimensional formula (and where to program this formula?) to indicate a symmetrical tolerance value as in the following examples:

0.0" - 0.250": Tolerance shall be ±0.010" 

0.251" - 0.375" Tolerance shall be ±0.020"

0.376" -
