change text size in block reference...help

December 1, 2022

hello friends:

Does anyone have a routine to modify the size of the texts in this block?

I want to modify these three text sizes for one that I previously decide.

somebody help me please.

block.dwg

Open in the block editor, make your changes then run attsync on it.

For a single block I would do as RonJon, just edit the block and attsync.

A LISP and other automation works best to do the same action many times with minimal user input. How many blocks are you wanting to change by the way? Is it just a single block, many, or do you need to do this frequently? (writing, testing and verifying that a LISP works as expected takes some time, which might not be a time saving if you are only ever going to do this once or twice)

It is not a single block, there are many and in many drawings, for that reason I am looking for a lisp

I found this but it changes the width and I'm looking to change the text size....:(

(vl-load-com)
(defun C:BTW ; = Block Text Width
(/ width blk ent)
(setq width (getreal "\nWidth factor for all Text/Attributes: "))
(setq blk (tblnext "block" t)); first one in Table
(while blk
(if (= (logand 20 (cdr (assoc 70 blk))) 0); not an Xref [4] or Xref-dependent [16]
(progn ; then -- process this Block
(setq ent (cdr (assoc -2 blk))); first object in Block definition
(while ent
(if (wcmatch (cdr (assoc 0 (entget ent))) "TEXT,ATTDEF")
(vlax-put (vlax-ename->vla-object ent) 'ScaleFactor width)
); if
(setq ent (entnext ent)); next object
); while
); progn
); if
(setq blk (tblnext "block")); next one in Table
); while
(command "_.attsync" "_name" "*"); update width in Block Attributes, if any
(princ)
); defun

I reckon..... if you read through the code.... (setq width .... ) gets the user to input the width - so if you look after that where 'width' is used it will give you a clue?

Aha!! "(vlax-put (vlax-ename->vla-object ent) 'ScaleFactor width)".. wonder what would happen if you took a guess and used "Height" instead of "ScaleFactor" ? Lets try.... if it all goes wrong wait for another to answer?

(defun C:BTH ; = Block Text Height
  (/ width blk ent)
  (setq width (getreal "\nHeight for all Text/Attributes: "))
  (setq blk (tblnext "block" t)); first one in Table
  (while blk
    (if (= (logand 20 (cdr (assoc 70 blk))) 0); not an Xref [4] or Xref-dependent [16]
      (progn ; then -- process this Block
        (setq ent (cdr (assoc -2 blk))); first object in Block definition
        (while ent
          (if (wcmatch (cdr (assoc 0 (entget ent))) "TEXT,ATTDEF")
            (vlax-put (vlax-ename->vla-object ent) 'height width)
          ); if
          (setq ent (entnext ent)); next object
        ); while
      ); progn
    ); if
    (setq blk (tblnext "block")); next one in Table
  ); while
  (command "_.attsync" "_name" "*"); update width in Block Attributes, if any
  (princ)
); defun

Though as it is, this routine does the change globally for all blocks in the drawing with no selection possible and all attributes in those blocks. It could be a good start for you to then ask "I found this, and changed it to modify text heights, but how could I get it to do this....?"

use this code to enter the desired height but it is manually, I would like to do it selecting by window.

remembering that the attribute is in a block reference

(defun C:test ( / e h )
(setq h (getdist "\nEnter height of text:"))
(repeat 100
(setq e (vlax-ename->vla-object (car (nentsel "\n Select an attribute to change:"))))
(vla-put-height e h)
); repeat
(princ)
)

December 2, 2022

Try this:

(defun c:foo (/ b c h n s)
  ;; RJP » 2022-12-02
  (cond
    ((and (or (setq h (getdist "\nEnter height:<1> ")) (setq h 1))
	  (setq s (ssget '((0 . "INSERT") (66 . 1))))
     )
     (setq b (vla-get-blocks (vla-get-activedocument (vlax-get-acad-object))))
     (setvar 'cmdecho 0)
     (foreach e	(vl-remove-if 'listp (mapcar 'cadr (ssnamex s)))
       (setq n (vla-get-effectivename (vlax-ename->vla-object e)))
       (or (member n c)
	   (progn (vlax-for a (vla-item b n)
		    (if	(= "AcDbAttributeDefinition" (vla-get-objectname a))
		      (progn (vl-catch-all-apply 'vlax-put (list a 'height h)) (setq c (cons n c)))
		    )
		  )
		  (command "_.Attsync" "Name" n)
	   )
       )
     )
     (setvar 'cmdecho 1)
    )
  )
  (princ)
)
(vl-load-com)

And with your code, use WHILE rather than REPEAT. Also check that the item has a height property AND can be modified before trying to set it.

(defun c:test (/ e h)
  (or (setq h (getdist "\nEnter height of text:<1> ")) (setq h 1))
  (while (setq e (car (nentsel "\nSelect an attribute to change:")))
    (if	(and (vlax-property-available-p (setq e (vlax-ename->vla-object e)) 'height)
	     (vlax-write-enabled-p e)
	)
      (vla-put-height e h)
    )
  )
  (princ)
)

Just a point, to put your code with the grey background use the <> button and copy it to the pop up window, it makes it easier to see what is code and what isn't

'Test' you posted doesn't change the block definition, just the text entered into the attributes - try and see, run it and set a height and then 'attsync' what you just changed, it pops back to how it was, similarly copy 2 of the same block and try it on one, it will only change the one you select.

December 2, 2022

FYI You will need to Regen to see changes if selecting with nentsel

(defun c:test (/ ADoc e h)
  (setq ADoc (vla-get-ActiveDocument (vlax-get-Acad-Object)))
  (or (setq h (getdist "\nEnter height of text:<1> ")) (setq h 1))
  (while (setq e (car (nentsel "\nSelect an attribute to change:")))
    (if (and 
          (vlax-property-available-p (setq e (vlax-ename->vla-object e)) 'height)
          (vlax-write-enabled-p e)
        )
      (vla-put-height e h)
    )
    (vla-Regen ADoc acActiveViewport)
  )
  (princ)
)

Just for fun... this is one I modified from Lee Macs AttCol LISP. All credit to him ( http://www.lee-mac.com/attributecolour.html )

This one will modify the text height in selected blocks (not the block definitions). I haven't changed the errors or anything like that, if it doesn't work as expected probably my fault

(Same way that your 'test' LISP does but not block definition that your BTW or RonJons FOO does)

Hi @Steven P, thanks for this but when I run an attribute sync on that block again the text reverts to its original.

I looked at the code but couldn't see anything that was causing this.

June 7, 2023

the first one I posted, BTH, or the 2nd one, AttHeight ? Attheight doesn't change the block definition, just the way that instance of that block is displayed - so when you attsync that it goes bat the block definition sizes . BTH should update the block definition, and so Attsync shouldn't affect it

June 7, 2023

AttHeight is the one that I'm using.

June 7, 2023

Yes, that one just changes the text height for that block instance and not the block definition.

I'd need to have a good think how to modify that to suit - not sure I'll get time to do that though! Maybe one of the other codes above will do what you want?

THIS modifies the block definition.

I ended up using this. I did like the dialog Steven used to allow the selection of each attribute but I'd say 999/1000 I'd need this.

I updated the code above so ATTSYNC will only be called once per block name.
