Hi.

I have some multiline attributes that contain strings that are longer than 250 characters. Someone that know how to empty the attribute using autolisp?

 

Thanks in advance.

Are there other attributes on the block besides the multiline?  or blank all attributes regardless if its multiline or not?

(defun c:begone (/ atr)(vl-load-com)
  (while (setq atr (car (nentsel "\nSelect Attribute:" )))
    		(vla-put-textstring (vlax-ename->vla-object atr) "")))
	 
(defun c:begonem (/ atr)(vl-load-com)
  (while (setq atr (car (nentsel "\nSelect Attribute:" )))
    		(if (eq (vla-get-MTextAttribute (setq atr (vlax-ename->vla-object atr))) :vlax-true)
    		(vla-put-textstring atr "")))
  )
  
(defun c:begoneML (/ ss)(vl-load-com)
  	(if (setq ss (ssget ":L" '((0 . "INSERT")(66 . 1))))
	  	(repeat (sslength ss)
		  (foreach itm (vlax-invoke (vlax-ename->vla-object (ssname ss 0)) 'Getattributes)
		    	(if (eq (vla-get-MTextAttribute itm) :vlax-true)
			  	(vla-put-textstring itm "")))
		  (ssdel (ssname ss 0) ss)
		  )))

(defun c:begoner ( / ss)(vl-load-com)
  	(if (setq ss (ssget ":L" '((0 . "INSERT")(66 . 1))))
	  	(repeat (sslength ss)
		  (foreach itm (vlax-invoke (vlax-ename->vla-object (ssname ss 0)) 'Getattributes)
		  			  	(vla-put-textstring itm ""))
		  (ssdel (ssname ss 0) ss)
		  ))
  )

Please try attached routine, select blocks, specify which attribute, then in the dialogue box set "Replace mode" as "New" and "New text" as a space.
