Dimension Tolerance Dialog Box

The Dimension Tolerance dialog box controls the dimension tolerance values and the display of noninteger dimensions.

The options available depend on the type of tolerance selected and whether you are setting document options or applying the specifications to selected dimensions. A window previews the dimension and the tolerances.

To open the Dimension Tolerance dialog box:

Click Tolerance in Tools > Options > Document Properties > Dimensions.

Callout value In TolAnalyst, when a dimension is a callout with more than one value, you can select a value and edit it.
Tolerance type Select one of the following from the list: None, Basic, Bilateral, Limit, Symmetric, MIN, MAX, Fit, Fit with tolerance, or Fit (tolerance only).

You can set Tolerance type to None and then set the variations and font to defaults for the current document.

When you modify the properties of a dimension, the default tolerance settings will be those set in these options.
Tolerance values Specify the Maximum Variation and/or Minimum Variation values as appropriate for the type of tolerance that you selected.
Dual dimension tolerance Select Inward rounding of secondary unit tolerance extents.

If the high end of the secondary unit’s tolerance rounds to a number that is larger than the displayed rounded number of the primary unit’s tolerance high end, the secondary unit’s high end is rounded down.

If the low end of the secondary unit’s tolerance rounds to a number that is smaller than the displayed rounded number of the primary unit’s tolerance low end, the secondary unit’s low end is rounded up.
Font Size/Fit tolerance font size Specify the font size to use for the dimension tolerance text. For Fit, Fit with tolerance, and Fit (tolerance only), Fit tolerance font size is available for the Hole Fit and Shaft Fit text.
