Coordinate Distance

Selection prerequisites: Two points.

Measures the distance between the two points based on the marked coordinate system. If there is no marked coordinate system, Sketchpad marks an existing coordinate system or creates a new one.

This command differs from the Distance command because the coordinate distance is based, not on physical distance (that is, not on inches or centimeters), but on the unit size of the marked coordinate system. A coordinate distance measurement has no units.
