Multileader Source Block will not update

[joshc96]

Try the code below. Replace the yournewblockname text below with the user block you're using. Paste the code into Notepad and saveas to asdf.lsp. Use APPLOAD to find and load that LSP file then enter the ASDF at the command line, select the blocks you want to change and they'll update. It worked with minimal testing...only took a few minutes to write.

(defun c:asdf (/ cnt newblockname obj ss)
  (setq    ss         (ssget '((0 . "MULTILEADER")))
    cnt         0
    newblockname "yournewblockname"
  )
  (repeat (sslength ss)
    (setq obj (vlax-ename->vla-object (ssname ss cnt))
      cnt (1+ cnt)
    )
    (vla-put-contentblockname obj newblockname)
  )
  (princ)
)

Try using this command:

(defun c:MI-ldrbc (/ ss);; Leader Block Change
   (princ"\n   Select Multileaders to change their Block")
   (setq ss(ssget '((0 . "multileader"))))
   (cond(ss
;;Replace in the next line "The UserBlock Name" with your user block name.
           (repeat(sslength ss)
               (vla-put-ContentBlockName(vlax-ename->vla-object (ssname ss 0)) "The UserBlock Name")
               (ssdel (ssname ss 0)ss)
           )
  ))
)
(princ "\n   Use the new command "mi-ldrbc" to apply changes.)

I hope that this is what you wanted.

This worked perfectly Isak!!! Thank you very much!

Thank you Josh but that changed the block for the original style as well and I need to use both styles in a drawing and need them to be independent of each other. Mishaeli Isak's routine seemed to do the trick.

As far as understand your question, all you need is to create a new multileader style and use that new one when you want to place the many many leaders with different call outs.

I know this is an old(er) topic, but this just worked for me (2024-05-15) when the MLEADER style used a custom block to start with.

Select the Multileader, in the PROPERTIES dialog box, in the BLOCK section, change the "Source block" field from "User block" to something else, and then change back to "User block".

A "Select Custom Content Block" dialog should pop-up allowing you to select the desired block.

NOTE - This DOES NOT change the MLEADER Style.

Does this change it for all 500 leaders, or just the one?
