Changing text height and style in AutoLISP

[ahipkin]

Is there a way to change the height and style of text in an AutoLISP program? Currently I have to do it manually (select the text and change the height in the Properties Box). This Forum has been a wealth of information for me in the past but I haven't seen anyone mention this specifically.

[Jeff_M]

Yes, this is a relatively easy program to write.

Select text objects
Cycle through the selection set
Modify the "Height" and "Stylename" properties using ActiveX OR
Modify the Assoc 40 & 7 lists of the entity list with subst & entmod
Voila! you're done!

HTH,
Jeff

Try this out....
New text height:

(defun c:CHGHT ()
    (graphscr)
    (prompt "text height to change")(terpri)
    (setq a (ssget))
           (setq nh(getreal "New Text Height . . ? "))
           (princ "\nWORKING\n")
        (setq N (sslength a))
          (progn
          (setq n1 N)
          (repeat N
            (setq n1 (- n1 1))
            (setq b (ssname a n1))
            (setq c (cdr(assoc 0(entget b))))
            (if (= c "TEXT") (progn
                (setq e (entget b))
                (setq f (assoc 40 e))
                (setq g (atof(rtos(cdr f)2 6)))
                (entmod (subst(cons(car f) nh) f e))

            ))
            ))

(princ)
)


New text style:
(defun C:CHGSTYLE ()
   (setq e (getstring "STYLE TO CHANGE TO? >>"))(terpri)
   (setq DEG (getreal "OBLIQUING ANGLE OF NEW STYLE?>>"))(terpri)
   (setq g (dtr deg))
   (setq gh (ssget))
   (setq gi (sslength gh))                 ;number of objects selected
   (setq gk gi)
   (repeat gi
      (setq gk (- gk 1))
      (setq gr (ssname gh gk))
      (setq gt (entget gr))
      (setq gj (assoc 0 gt))
      (setq gl (cdr gj))
      (if (= gl "TEXT")
          (EDITLIST)
   )  )
(princ)
 )

(defun EDITLIST ()
            (setq b gt)
            (setq d (assoc 7 b))
            (setq d1 (cons (car d ) e))
            (setq b1 (subst d1 d b))
            (setq f (assoc 51 b1))
            (setq f1 (cons (car f ) g))
            (setq b2 (subst f1 f b1))
            (entmod b2)
)

Enjoy!

Or here's an example using Activex

(defun c:fixtext ( / ss1 index newht newstyle styledata defwidth ename txtobj)
(setq ss1 (ssget (list (cons 0 "*text")))
      index 0
      newht (getstring "\nEnter new height for text: ")
      newstyle (getstring "\Enter new style for text: ")
)
(if (setq styledata (tblsearch "style" newstyle))
    (progn
       (setq defwidth (cdr (assoc 41 styledata)))
       (while (setq ename (ssname ss1 index))
              (setq txtobj (vlax-ename->vla-object ename))
              (vlax-put-property txtobj 'Height newht)
              (vlax-put-property txtobj 'StyleName newstyle)
              (if (vlax-property-available-p txtobj 'ScaleFactor)
                  (vlax-put-property txtobj 'ScaleFactor defwidth)
              )
              (setq index (1+ index))
       )
    )
    (princ "\nRequested text style does not exist!")
)
(princ)
)

Can this work for MText? If not, can it be added. Also, how would you added this to your cad?

Here is a similar routine that could be used as a template to create routines that change text height style or whatever

Peter Jamtgaard

(defun C:CHW (/ inCount sngTextWidth ssSelections objSelection)
 (princ "\nSelect text entities to modify text width: ")
 (setq ssSelections (ssget (list (cons 0 "TEXT,ATTDEF")))
       sngTextWidth (getdist "\nEnter text width: ")
 )
 (if (and ssSelections
          (> sngTextWidth 0.0)
     )
  (repeat (setq intCount (sslength ssSelections))
   (setq intCount     (1- intCount)
         objSelection (vlax-ename->vla-object
                       (ssname ssSelections intCount)
                      )
   )
   (vla-put-scalefactor objSelection sngTextWidth)
  ) 
 )
 (prin1)
)

The code I posted earlier will work for MTEXT, provided the formatting hasn't been applied in the MTEXT Editor. If it has there's a routine called STRIPMTEXT.LSP which will remove the formatting. It can be found at:

If you're not familiar with customising AutoCAD, the easiest way to add these commands to your setup is to go to Tools>Load Application and add them to the Startup Suite.
