I'm now receiving the 403 error when attempting to post an embedded link to another post on the forum.

 

When you say "embedded", do you mean like in my post above or something different?

After a few more tweaks. Testing paulmcz's code:

;;; Measures distance between 2 points, along polyline

(defun c:lm (/ a b d e d1 d2 p pl oecho osn)
  (vl-load-com)
  (command "cmdecho" (getvar "cmdecho"))
  (setq oecho (getvar "cmdecho")
	osn (getvar "osmode"))
  (setvar "cmdecho" 0)
  (setq e (entsel "\n Select polyline to measure on: ")
	pl (car e))
  (if e
  (cond	((= (setq p (cdr (assoc 0 (entget (car e))))) "LWPOLYLINE")
	 ;(setvar "osmode" 2)
	 (setq a  (getpoint "\n Select first point on polyline: ")
	       b  (getpoint "\n Select second point on polyline: ")
	       d1 (vlax-curve-getDistAtPoint pl a)
	       d2 (vlax-curve-getDistAtPoint pl b)
	       d  (abs (- d1 d2))
	 )
	 (princ (strcat "\n Distance = " (rtos d 2 5)))
	)
	(t (alert "Selected object is not a polyline"))
  )(alert "Nothing selected"))
  (setvar "osmode" osn)
  (setvar "cmdecho" oecho)
  (princ)
)

OK, that seems to have worked.

 

Please use this thread to post other code snippets so we can make sure it will work more generally - thanks.

There is some background to this. The web hosting company are implementing tougher security measures to keep sites like CADTutor safer from exploits like cross site scripting. However, the new security measures need to be tweaked to differentiate between "good" code and "bad" code in an attempt to find the right balance between security and usability. I think we are now close to having this sorted out but please post in this topic to report any 304 errors that you see and let me know what you were trying to post when the error occurred.

OK, I am testing again:

(defun c:mc (/ a b c f f0 f1 d d1 d2 e1 n oerr osn oecho)

  (setq oecho (getvar "cmdecho")
        osn   (getvar "osmode"))
  (setvar "cmdecho" 0)

  (setq	f1 (entsel "\n Select circle to copy props + diameter from: ")
	f0 (entget (car f1))
	f  (cdr (assoc 40 f0))
	c  (cdr (assoc 0 f0))
  )
  (redraw (car f1) 3)
  (if (equal c "CIRCLE")()(^C^C))
  (princ "\n Select circles to change: ")
  
  (setq a (ssget '((0 . "circle")))	; filters in circles only
        d (sslength a)			; = number of circles in ss
        d1 d)
  (repeat d
    (setq d2 (1- d1)
          n  (ssname a d2)		; = last entity in ss
          e1 (entget n))
    (entmod (subst
	       (cons 40 f); f= new radius
	       (assoc 40 e1)
	       e1
	     )
    )
    (setq d1 d2)
  )
  (command "matchprop" f1 a "")
  (setvar "osmode" osn)
  (setvar "cmdecho" oecho)
  (princ)
)
