;;; DESCRIPTION
;;;
;;; ENDTICK inserts and aligns the ENDTICK block at the endpoint of every arc or line
;;; in a selection set. It removes duplicate ticks.
;;;
;;; ENDTICK is useful for surveying and civil engineering plans to demarcate points of
;;; curvature, tangency, et cetera.
;;;
;;; You can make your own ENDTICK block if you prefer some custom shape or size tick.
;;; The default ENDTICK block is a one unit long vertical line with its insertion point
;;; at its midpoint. ENDTICK scales the ticks to the dimension text height
;;; (dimscale * dimtext), so the default ENDTICK block will look as big as the current
;;; dimension text height.
;;;
;;; Revisions
;;; 20060914 TGH Version 1.0PR released. 3 hrs. Works only with world UCS and View
;;; Modified by Irn?Barnard on 2010-01-15 to allow for polylines as well, noted with comments starting with IB:
