Apply Defaults Based on area
The Apply Defaults Based On area lets you apply default dimension tolerances either based on feature type or on the number of decimal places displayed.
Selecting the Feature Type option enables the Default Feature Tolerance area, allowing you to define dimension tolerances based on individual feature types. Whenever PC-DMIS creates a dimension automatically, either because the Auto option is selected in the Location dialog box (Insert | Dimension | Location) or because you used the Auto Dimension Setup button, the default dimension tolerance associated with that feature type is used. See the "Default Feature Tolerance" topic.
Selecting the Decimal Place option enables the Default Tolerances area, allowing you to define dimension tolerances based on the number of decimal places. This is the old way that PC-DMIS determined dimension tolerances. See "Default Tolerances" topic.
