Center Text in Box - From ENTSEL to SSGET?


Recommended Posts

I found this code on the web somewhere and it works great for a single line of text. I would like to be able to select multiple lines of text and have it do the same.


To center several lines of text in an existing rectangle.

I am hoping someone already has code to do this rather than hoping someone

would code it for me. I am clueless on how to do this.. :oops:


Many times what I encounter is multiple lines of individual text items.

So it may be TEXT or it may be MTEXT.


Here is the existing code which works great for a single line of text:


; By G. Ramesh, NPCC, Abu Dhabi.

(defun c:CTT(/ e el p1 p2 mid tb sp ll ur mid1 dis)

(Princ "\nCenter Text in Box. ")

(setvar "cmdecho" 0)

(setq e (car(entsel "\nPick the text: ")) 
    el (entget e))

          (initget "Window Circle")

(setq opt (getkword "\nTo be enclosed within a Window/Circle <W>: "))

(if (or (not opt) (= opt "WINDOW"))
(setq p1 (getpoint "\nFirst corner of the enclosing box: ")
     p2 (getcorner p1 "\nOther corner: ")
    mid (polar p1 (angle p1 p2) (/ (distance p1 p2) 2))

(setq mid (cdr(assoc 10 (entget(car(entsel "\nSelect a CIRCLE: "))))))

(setq tb (textbox el) sp (cdr(assoc 10 el))
     ll (mapcar '+ (car tb) sp)
     ur (mapcar '+ ll (mapcar '- (cadr tb) (car tb)))
   mid1 (polar ll (angle ll ur) (/ (distance ll ur) 2.0))
    dis (mapcar '- mid mid1)

(command ".move" e "" dis "")


Apologies for the formatting being all wonky, it was like that...


Thanks much!

Thanks for the reply but, that code does the same thing as mine...

(A single line of text)


I want to be able to select multiple lines of text (ie:SSGET)


The code needs to determine the "center point" based off of

how many items were selected and their respective heights.

If it needs to change the justification that would be fine.

I found this code on the Autodesk Forums...


It "somewhat works."


With this code, the text has to lie somewhere inside the rectangle already.

It centers the text but multiple lines are ALL placed in the center on top of each other.

Doesn't work with MTEXT though.


(defun c:CenterText (/ ss i elast obj bent ipt)
 (defun getmid (ent)
   (setq lst (mapcar 'cdr (vl-remove-if-not '(lambda (x) (= 10 (car x))) (entget ent))))
   (if (= (length lst) 4)
     (mapcar '(lambda (a b) (/ (+ a b) 2.)) (car lst) (caddr lst))

 (command "_undo" "begin")
 (prompt "\Selext text within the table.")
 (setq ss (ssget "_:L" '((0 . "TEXT"))))
 (setq i -1)
 (while (setq ename (ssname ss (setq i (1+ i))))
   (setq obj (vlax-ename->vla-object ename))
   (setq elast (entlast))
   (setq ipt (vlax-get obj 'insertionpoint))
   (if (vl-catch-all-error-p
           '(lambda ()
              (vl-cmdf "_-BOUNDARY" (trans ipt 0 1) "")
              (while (> (getvar "CMDACTIVE") 0) (command ""))
     (princ "\nText boundry not found.")
     ;;  got a boundry
       (if (and (not (eq elast (setq bent (entlast))))
                (setq midpt (getmid bent))
           (vla-put-Alignment obj acAlignmentMiddleCenter)
           (vla-put-TextAlignmentPoint Obj (vlax-3D-point MidPT))
         (and (eq bent (entlast)) (entdel bent))
 (command "_undo" "end")

Found a modified version of the above code.

This works perfectly IF the text is MTEXT.

I had to add the ERASE command line since it drew in

a bounding box and then left it there.


All you Master-Coder-Dudes probably laugh at my duct tape fix but it works..


It still places individual TEXT items all on top of each other in the center. :-\


So close...

If you take multiple lines of text the way you see them is not necessarily the order a ssget will return you need to sort the lines of text say based on the Y value of the text insertion lower left. Once you have this new order list it would be easy to place inside a box. Stuff like line spacing still to be worked out.


Anyone sort this ?

((y1 text1)(y2 text2)(y3 Text3)) correct is ((y2 text2)(y3 text3)(y1 text1))

The above should work with both Text & MText at any rotation angle & with any justification.


If the text is to be aligned, use my Align Text program before using the above (and use the JUSTIFYTEXT command before that if the text has varying justification settings).

Assumptions & Notes:

  • Assumes all text in the selection has the same rotation.
  • Assumes WCS (not tested/designed for all UCS/View settings)

Is it possible to change this to centre the text/mtext between two selected points?


Sometimes it's desirable to centre the *text to part of a block or a non rectangular polygon or even simply between two entities.


I did try to work out where the second part of the move command was, but I'm baffled


Thanking someone in anticipation

No time to test it, but try changing this:

            (setq p (LM:ssget "\nSelect polyline: "  '("_+.:E:S" ((0 . "LWPOLYLINE")))))


            (setq p (getpoint "\nSpecify 1st point: "))
           (setq q (getpoint "\nSpecify 2nd point: " p))


And this:

                    (mapcar 'cdr
                       (vl-remove-if-not '(lambda ( x ) (= 10 (car x)))
                           (entget (ssname p 0))


                    (list p q)

That's peculiar, I'm sure that it worked great yesterday. After using the modified lisp a few times I notice a slight error.


Please Lee, if you ever find a spare few minutes....

Are you reading the coordinates of the text alignment point or the center of the bounding box of the text object?


Note that the program is positioning the text based on the center of the bounding box, not the text alignment point.

The leader is on the alignment point..


I was just thinking that the lisp calculates the centre of the text from the overall size of the text entity, in which of course the insertion point may not be the same as the centre of the text depending what characters are within the string.

I just realized that I had never gotten back after trying this routine out... :oops:


Like all your stuff, it works great!



For this and all that you have helped me with over the years...
