In the Parameters dialog box you can pick the value in the Equation column.
When the value is selcted the arrow pulldown menu will appear and you can
set the tolerance here as well.
The Tol. column is used to quickley set the dimension at its min, max, and
nominal field.
I agree that it should be easier to find information through the help. It's
there if you know what to look for, but there's no tutorials for it.
