To specify the default angular filter for GD&T items:
- Click Measure tab > Current panel > Parameters.
- In the Measure Parameters dialog, select the GD&T tab.
For example, for GD&T Perpendicularity items, an angular tolerance of three degrees restricts the available datums to items that are within three degrees of the perpendicular of the feature to be checked.
Note: You can override the default angular tolerance in the
Item Definition dialog of each GD&T item.
