Polyline question...

[goldy2000]

Hy everyone!!! I have a problem, I draw polyline (2D) and need lisp that ''reads'' my pline and extract ''pick points'' with coordinates (X,Y in this case there is no Z coordinate), so these points must extract to new file txt/csv/xls, or just to put points on that polyline... Maybe this question is solved in the past on this forum...but didn't find it...anybody????

Is this LISP routine what you're looking for?

Or look this

Export of coordinates of the specified points, the chosen objects: points, blocks, polylines, splines in a text file or Excel.
Text file — txt, or csv.
A rounding off of coordinates according to current adjustments of a command _UNITS (LUPREC system variable)
3 commands Are certain
COOR - export of coordinates
COORN-export of coordinates with numbering. Numbers of points are drawn by the text on the current layer, the current style, current height (TEXTSIZE)
COORT-export of coordinates with numbering where number considers the text nearest to a point

Thx for posting that, I already used that lisp, and it helped me...but is there a option when I draw pline, lisp puts dots on insertion places on that pline?? and after that I use COOR lisp and pick up all that coordinates (I need that because i need manually enter Z coord in that particular places)...THX for posting hyperlink..

Give it a shot. It save on ".csv" format, separated by ","

(defun c:plex()
  (setq el (entget (car (entsel "\n Select the pline to extract: "))))
  (setq file (open (getfiled "Output file" "" "csv" 9) "w"))
  (repeat (setq i (length el))
    (if (= (car (setq l1 (nth (setq i (1- i)) el))) 10)
      (write-line (strcat (rtos (cadr l1)) "," (rtos (caddr l1))) file)
      )
    )
  (close file)
(princ)
)

Late.... =)

Hey man, I tried it, and this lisp only export points (it has only one function), VVA posted what I was looking for, THX for your time

If I have correctly understood, command COORNP is necessary to you

Hmmm, sounds good VVA, but can explain little bit more??
COORNP means coordinate numbering (COORN lisp helps here) and what is P meaning?? point?? or doting the exact place of polyline inflection?? hmmm...

Are you looking to just extract the Vertex point of an LWPOLYLINE and write these to Excel?
