Feature Extraction - Ring Band

The Ring Band area is used to calculate the feature’s projection plane and normal vector. The feature data will be projected up into the ring band's plane. The following Ring Band controls are used to accomplish feature extraction for circles, round slots and square slots:

Enable: When this option is selected, the Ring Band options will take affect. When disabled, the default values will be used: Inner Offset - 1.2x the theoretical value and Outer Offset - 5 more millimeters/inches than the Inner Offset value.

Inner Offset: Provides the offset from the theoretical feature radius or form for the inner edge of the ring band. This value is expressed in part program units and must be greater than or equal to zero (a value of zero means an inner edge of the ring band coincides with the feature nominal.) See Image below.

Outer Offset: Provides the offset from the theoretical feature radius or form for the outer edge of the ring band. This value is expressed in part program units and must be greater than the Inner Offset value. See Image below.
