Change attribute width factor in several blocks

[Designer_1E]

Hello,

I've been searching all over for a LISP that can change the width factor of an attribute across dozens of blocks at a time?  The closest I have found is one that will change one attribute in one block at a time.  However i need to do hundreds.

We are forced to use blocks from a manufacturer that has an important attribute set at 0.5 width factor, and it is completely unreadable.  I have tried changing the overall text style, but it does nothing.  I can change them one at a time with BATTMAN, but like I said I need to do hundreds, repeatedly.

Please help.  Thanks.

Change the width to what?

Do you want to change the block references or the block definitions and then attsync?

Attached is a lisp file that combines two routines, either changing the Block Definitions and then attsyncing; or changing ALL attributed Block References in the drawing. Changing the References will omit any constant attributes as these are defined in the block definition, but this doesn't require an attsync. Block References on locked layers will not be honoured, i.e. they will be changed.

@Designer_1E  hi,

 I can change them one at a time with BATTMAN, but like I said I need to do hundreds, repeatedly.

Not true! if you use BATTMAN to set a new width to an attribute it will instantly change all the reference attributes in the current drawing (in all block references) this action is nearly the same if you edit the block with bedit and change an attribute width. why nearly? cause you also need to do attsync.

so if you did that and it did not reflect the attributes, then maybe you are missing the attribute or the attribute is in lock layer?

What are your requirements? An accurate answer will determine the type and scope of program you need.

- Block definition?

- Block reference?

- All attributes in block or a specified list of attributes?

    - if a list, provide the list

- All blocks or a specified list of blocks?

    - if a list, provide the list

- Multiple drawings?

    - all drawings in a project or a list of drawings?

    - no need to provide list

- Multiple projects?

Here is a sample for a drawing wide program for all attribute references only. I doubt this will suit your needs, but it's a starting point

(progn
  (setq ent (entnext))
  (while ent
    (setq et (entget ent))
    (if (= "ATTRIB" (cdr (assoc 0 et)))
      (progn
        (entmod
          (subst
            '(41 . 1)
            (assoc 41 et)
            et
          )
        )
        (entupd ent)
      )
    )
    (setq ent (entnext ent))
  )
)

This. is. amazing!  Thank you.

It was the definitions I really wanted, but it is great to have a choice!  You would not believe how many hours this will save me.

Hi Moshe,

BATTMAN does work.  It's just that I don't want to do it over, and over, and over again for each unique block.

No problem. Attached is an updated version where "Definitions" is the default value when prompted for "Definitions" or "References".

this is a good program. But what if I want to just change one specific attribute inside the block?
