Annotations are a way to display the deviation for a specific location on a surface colormap with its associated color.
For DCC systems, this parameter controls how far beyond the nominal feature’s dimensions the probe scans along both the major and minor axis of the feature. The default value is 2.0 mm. If you measure features whose actual location may vary significantly from their theoretical values, you need to increase this value to ensure that PC-DMIS measures the entire feature.
The Overscan value does not perform the clipping of the data. The Feature Based Clipping area in the Feature Extraction tab handles clipping. For information, see the "Feature Based Clipping Parameters" topic.
For a DCC laser Cylinder or Cone feature, the Overscan value should be a negative value.
For a laser Stud feature (see the laser Cylinder for stud information), the Overscan value should be a positive number.
