Subject: Controlling dimension tolerances

You can create dimensions as either tolerance or limits dimensions. When creating a tolerance dimension, you can control the upper and lower tolerance limits as well as the number of decimal places of the dimension text. The image tile on the right side of the Dimension Styles dialog box shows the appearance of tolerance and limits dimensions based on the current dimension style settings.  


Tolerance dimension.


Limits dimension.


The display of zero tolerance values depends on the measurement units.
Metric drawings follow the Metric ISO Dimension Standards and display zero toler­ance values without a plus or minus sign (0.0). For Imperial drawings, zero tolerance values display with a plus or minus sign (+0.0 or -0.0). To check the drawing mea­surement type, use the MEASUREMENT system variable.
