To Change the Tolerance Class

Each ISO-standard model has an extra attribute called the tolerance class, which determines the general coarseness of the model.

The configuration file option tolerance_class sets the default tolerance class for ISO models (the default is medium). The system uses the tolerance class together with the dimension value when retrieving tolerances for General or Broken Edge dimensions.

1. Click File > Prepare > Model Properties. The Model Properties dialog box opens.

2. Click change in the Tolerance line. The TOL SETUP menu appears.

3. Click Model Class.

4. From the TOL CLASSES menu, select a class name.

5. All dimensions driven by the General or Broken Edge table obtain new tolerance values. Regenerate the model.
