Summary
This command is used to place a Center Mark on Circle or Arc objects in the active Draftsman document (*.PCBDwf ). When placed, the Center Mark object detects and locks to the center point (radius origin) of the Circle or Arc and is then available as a reference location for placed dimension objects.
