   dimension the base point of objects that cannot be set in the AEC dimension style (creates an associative dimension)	select multiple objects.
   dimension OSNAP points on objects (creates an associative dimension)	verify that OSNAP is turned on. Enter p (Pick Points) on the command line, and select points on objects by snapping to them.
   dimension non-associative points in the drawing (creates a non-associative dimension)	verify that OSNAP is turned off. Enter p (Pick Points) on the command line, and specify points in the drawing.
