You can switch between a ray and an xline by specifying turning the Ray Mode off and on (AMCONSTSWI command, Find). A ray is a construction line extending to infinity in one direction only. An xline is a construction line extending to infinity in both directions. When the ray mode is turned on the icon for this command changes to Find.
