### Legacy (I,J,K, X,Y,Z) RMEAS Mode

The Legacy (I,J,K, X,Y,Z) RMEAS mode takes into account the orientation of the reference feature.

To understand this, examine an Auto Circle with three sample hits. PC-DMIS first takes three hits on the surface around the circle and then measures the circle based on the plane's location and the surface normal vector's orientation. Therefore, if the plane is at a 45 degree angle, PC-DMIS also measures the Auto Circle at a 45 degree angle.

Similarly, if the relative measure feature is rotated from its original orientation, then the associated feature will also be measured with the same rotational offset.

Legacy mode is also slightly smarter than Default mode, because when it looks at the reference feature it only offsets the main feature by valid axes for the reference feature type. For example, for a plane it doesn't make much sense to shift in all directions, but only by the plane's normal vector.

The Edit window command line for this option reads:

RMEAS/LEGACY (I,J,K, X,Y,Z)

Legacy mode should only be used in rare instances where adjustments in both orientation and position are needed.
