Count text inside Closed polyline

Can we count text or block inside the closed polyline using Autolisp.

Yes - retrieve the list of vertexes of said boundary polyline (ASSOC) and create a selection set using SSGET with Fence mode; don't forget to filter for desired entities (*TEXT and/or INSERT). Use SSLENGT to count your selection set or parse it for a more detailed result.

This will work well if the polyline is made by only straight segments; if there are arc ones will need to refine the Fence path by adding extra points on curved parts.

I m new to Lisp can you just code it to me.

you can use this for text.

(defun c:txt(/ CNTXT GTXT TXTC)
 (setq gtxt(ssget '((0 . "text"))))
 (setq cntxt(sslength gtxt))
 (setq txtc(strcat "count of text = "(rtos cntxt)))
 (alert txtc)
 (princ)
)

and this for block.

(defun c:blk(/ BLKC CNBLKT GTBLK)
 (setq gtblk(ssget '((0 . "insert"))))
 (setq cnblkt(sslength gtblk))
 (setq blkc(strcat "count of block = "(rtos cnblkt)))
 (alert blkc)
 (princ)
)

Not sure ab Fence mode, but I would surely use either Window Polygon or Crossing Polygon...

M.R.

Change the "insert" to count for text.

(defun c:test (/ e)
(if 
  (= (cdr (assoc 0 (setq e (entget (car (entsel "Pick a polyline:")))))) "LWPOLYLINE")
  (alert 
    (strcat "Number of blocks inside of polyline:   " 
      (itoa  
        (sslength
          (ssget "_WP" 
            (mapcar 
              (function 
                (lambda (x) (cdr x))
              ) 
              (vl-remove-if-not 
                (function 
                (lambda (x) (= (car x) 10))) e)
            ) '((0 . "[color="red"]INSERT[/color]"))))
      )
     )
   )
 )
)

Agreed, Marco

An extra I will have to find it but pretty sure posted code here for text inside plines may be 12 months old like above uses the "WP" with polygon option to find text.
