select inside of a polyline

Hello everybody,

Is it possible to select inside of a polyline? Thanks!

Have you tried "PSELECT" then type in "WP" or any other options.

Its not worth your time Jeep, this has already been answered here

My 5 cents

(defun C:ICS (/ en ss lst ssall tmp head)
 ;;InSide Contour Select

 (vl-load-com)
 (if (and (setq en (car (entsel "\nSelect contour: ")))
          (wcmatch (cdr (assoc 0 (entget en))) "*POLYLINE")
     ) ;_ end of and
   (progn
     (setq lst (ACET-GEOM-OBJECT-POINT-LIST en 1e-3))
     (setq lst (mapcar '(lambda (x) (list (car x) (cadr x))) lst))
     (while lst
       (setq head (car lst)
             tmp  (cons head tmp)
             lst  (vl-remove-if
                    '(lambda (pt) (equal pt head 1e-6))
                    (cdr lst)
                  ) ;_ end of vl-remove-if
       ) ;_ end of setq
     ) ;_ end of while
     (setq lst (reverse tmp)) ;_ end of setq
     (ACET-SS-ZOOM-EXTENTS (ACET-LIST-TO-SS (list en)))
     (command "_.Zoom" "0.95x")      
     (if (setq ss (ssget "_CP" lst))
       (sssetfirst ss ss)
     ) ;_ end of if
   ) ;_ end of progn
 ) ;_ end of if
) ;_ end of defun 
(princ "\nType ICS") 

Nice lisp, VVA! Can you add option to select or not those objects intersecting the polyline? Those one that are/are not completely inside the poly...?

Other variant (add Outside contour select )

PS

If you delete or commented out Blue line, then the contour can be also a circle, ellipse, spline

thank you!

Sorry to resurrect this thread. I have been using this ICS command quite a bit over the last several months. Now all of a sudden it stopped working. Every time I select a polyline, it hangs for a few seconds and then gives the following:

Hard error occurred ***

internal stack limit reached (simulated)

I am using AutoCAD 2007 and have even tried re-installing it to try to correct the issue with no luck. I also tried another computer and it has the same problem.

Any help will be greatly appreciated. This has become one of my favorite commands and now I feel like I lost a finger.

EDIT: So I ran it through VLINE and found which line it was breaking at. It stopped at (list en) in the line below. After commenting it out, it worked.

;; (ACET-SS-ZOOM-EXTENTS (ACET-LIST-TO-SS (list en)))

Thanks,

KoKos

This routine is very useful. Would It be possible to add an option to select multiple objects instead of only one, as in Tharwat's routine? The linked routine is missing the OCS option, and interactive CP/WP option, which I appreciate.
