### Change Tolerance

The Change Tolerance icon is available to the Text, Chart, CAD, Custom Report, and Report tabs. It displays a selectable list of available tolerances defined for the selected feature variable (or variables). When selected, the software uses any tolerance values associated with the chosen list item instead of the default.

This list contains two permanent items, Default and Temp.

Note: You must apply data for a feature variable (or variables) for which the custom tolerance has been defined; otherwise, selecting the tolerance item does nothing.

If no additional tolerance settings are defined, you will only see Default and Temp listed.

Using the Temporary (Temp) Tolerance

The Temp item lets you define a temporary, on-the-fly tolerance that is applied to all variables no matter which part it belongs to. Selecting this item opens the Temporary Tolerance Assignment dialog box.

Initially, the dialog box does not have any tolerance values defined and the check boxes are unmarked. Define the tolerance values you want to use; then mark the check box next to the each tolerance you want to use and click Apply.

In order for the tolerances to be applied, the check box must be marked; otherwise, the default tolerance is used.

For example, if you set the Upper tolerance to 1 but clear its associated check box, that tolerance is not used. The software uses the default upper tolerance for those feature variables instead.

Defining Variable Tolerances

These tolerances are defined by right-clicking on the variable (or variables) in the Data Editor tab and choosing Edit Variables. See "Editing Feature Variables" in the "Data Editor Tab" section for more information.
