Add Polyline Vertex

[CAD_Noob]

Does anyone have a lisp that can add multiple vertex for polyline?

I found this Lisp from the great @Lee Mac and it works except that I need to be able to pick simultaneously even if it does not reside on the line then hit escape or enter when done. I will then move the added vertex to its proper location.

can it be modified so i can pick multiple points until I exit?

So is your question really how to make these loop, keep picking points until you hit enter or escape?

Since Lee's Code only has you picking a point its easy enough. Just add a call at the end of APV (line 95) to call itself again.  This will force a loop that you have to hit esc to exit.

This is  a better option. Has undo marks.  You could also set your snaps before entering the command if you want to.

;; Add Polyline Vertex loop
;; Dependent AddLWPolylineVertexV1-1.lsp
(defun C:APVL ( / )
  (vl-load-com)
  (princ "\nStarting Add Polyline Vertex loop. Press ESC to stop.")
  (vla-StartUndoMark (setq doc (vla-get-ActiveDocument (vlax-get-Acad-Object))))  
  ;(setvar 'OSMODE 3) ;End and mid point snaps
  (while T
    (C:APV) 
  )
  (princ "\nAdd Polyline Vertex Loop ended.")
  (vla-EndUndoMark doc)
  (princ)
)

Or just call MULTIPLE before calling APV.

A friend of mine got me this vlx file but there is an annoying pop-up
