Set DTEXT TextAlignmentPoint to bottom center

[3dwannab]

Hi all,

 

I'm struggling to set DTEXT justification to bottom centre. I've put the alignment to bottomcenter in the code below but it's the alignment point I'm having difficulty with.

 

MTEXT is much more straight forward it seems.

 

(setq obj (vlax-ename->vla-object (setq en (car (entsel)))))
(setq ent (entget en))

(cond 

  ;; If it's TEXT
  ((eq (cdr (assoc 0 ent)) "TEXT")
   (princ "\nIS TEXT\n")
   (vla-put-Alignment obj acAttachmentPointBottomCenter)

   ;; Having trouble with DTEXT to set the TextAlignmentPoint to bottom center
   (vla-put-TextAlignmentPoint obj (vlax-3d-point 0 0 0))
  )

  ;; If it's MTEXT
  ((eq (cdr (assoc 0 ent)) "MTEXT")
   (princ "\nIS MTEXT\n")
   (vla-put-AttachmentPoint obj acAttachmentPointBottomCenter)
  )
)

Try

(vla-put-Alignment obj 'acAttachmentPointBottomCenter)

 

You may be able to use a number also 1-9 rather than acAttachmentPointBottomCenter  2 or 8, not tested but works with some VL commands.

This?

(setq obj (vlax-ename->vla-object (setq en (car (entsel)))))
(setq ent (entget en))

(cond 

  ;; If it's TEXT
  ((eq (cdr (assoc 0 ent)) "TEXT")
   (princ "\nIS TEXT\n")
    (setq pos (vla-get-InsertionPoint obj))
    (vla-put-Alignment obj 13)
    (vla-put-TextAlignmentPoint obj pos)
  )

  ;; If it's MTEXT
  ((eq (cdr (assoc 0 ent)) "MTEXT")
   (princ "\nIS MTEXT\n")
   (vla-put-AttachmentPoint obj acAttachmentPointBottomCenter)
  )
)

Thanks, yes, it does indeed work but I found a piece of code in Lee Macs DynamicTextAlign program that doesn't change the location of the DTEXT. So full credit to him for that once again.

 

With your example, it shifts the DTEXT to another position.

 

(setq obj (vlax-ename->vla-object (setq en (car (entsel)))))
(setq ent (entget en))

(cond 

  ;; If it's TEXT
  ((eq (cdr (assoc 0 ent)) "TEXT")
   (princ "\nIS TEXT\n")
   (vla-put-Rotation obj 0) ;; Set text rotation to 0
   (vla-put-Height obj (getvar "textsize")) ;; Set text rotation to 0

   ;; Alignment Taken from DynamicTextAlign by LeeMac
   ;; 8 below is bottomcenter
   (if (eq AcAlignmentLeft (vla-get-Alignment obj)) 
     (progn 
       (setq tmp (vla-get-InsertionPoint obj))
       (vla-put-Alignment obj (+ 8 5))
       (vla-put-TextAlignmentPoint obj tmp)
     )
     (vla-put-Alignment obj (+ 8 5))
   )
  )

  ;; If it's MTEXT
  ((eq (cdr (assoc 0 ent)) "MTEXT")
   (princ "\nIS MTEXT\n")
   (vla-put-Rotation obj 0) ;; Set text rotation to 0
   (vla-put-Height obj (getvar "textsize")) ;; Set text height to 0
   (vla-put-Width obj 0) ;; Set text width to 0
   (vla-put-AttachmentPoint obj 8)
  )
)

That's what I did have. It's the vla-put-TextAlignmentPoint which needs to be there to alter the justification after vla-put-Alignment.

Not sure if this is any help, I use these to justify text (single command, example JUBC - JUstify Bottom Centre). Should also work with a single entity rather than a selection set.

 

(defun c:jul()  (jut  "l"))
(defun c:juc()  (jut  "c"))
(defun c:jur()  (jut  "r"))
(defun c:jutl() (jut "tl"))
(defun c:jutc() (jut "tc"))
(defun c:jutr() (jut "tr"))
(defun c:juml() (jut "ml"))
(defun c:jumc() (jut "mc"))
(defun c:jumr() (jut "mr"))
(defun c:jubl() (jut "bl"))
(defun c:jubc() (jut "bc"))
(defun c:jubr() (jut "br"))

;;https://www.cadtutor.net/forum/topic/35569-text-justification-lisp/
(defun jut (just / ss)
  (princ (strcat "\nSelect Text"))
  (if (setq ss (ssget "_:L" '((0 . "ATTDEF,MTEXT,TEXT"))))
    (command "_.justifytext" ss "" just)
  )
  (princ)
)

Thanks Steven, neat idea. I've got this one sorted with the help of Lee Macs code.

Look carefully at these 2 lines they are different. Often a quote is needed.

(VLA-PUT-ATTACHMENTPOINT OBJ ACATTACHMENTPOINTBOTTOMCENTER)

VLA-PUT-ATTACHMENTPOINT

 

This bit is fine in my code in the starting post.  vla-put-AttachmentPoint is for MTEXT only which is working fine.
