In another forum, a member named Ollie was nice enough to write a piece of lisp to add to the "endtick.lsp" I found above, which adds polyline capabilities to the lisp. The only thing is I am not yet familiar with lisp enough to know where to insert it into the "endtick.lsp". Is there anyone who can help me combine the two. Also at the end of this it has a line of text that says "add your tick here" not sure if I need to do anything with that. The endtick.lsp I found uses endtick.dwg.
Code:
;;Not tested
;Get ent
(setq ent (vlax-ename->vla-object (car(entsel))))
;get coordinates
(setq coords (vla-get-coordinates ent))
;get vertice count
;--There is probably a ubound function to get the limit
(setq limit (/ (length(vlax-safearray->list(vlax-variant-value coords))) 2))
;set counter
(setq cntr -1)
(while(< (setq cntr (1+ cntr)) limit)
(if(/= (vla-getbulge ent limit) 0,0)
(progn
; the cntr value is the index of a bulge if the condition is met
(setq tickPoint (vla-get-coordinate coords cntr))
;add your tick here
)
)
)
Here is the "endtick.lsp" content
(In order to use it you must use the "endtick.dwg" as well because it creates the "tick" style drawn.)

;;; 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.
;;;
