How do I delete a block listed in the blocks palette from my drawing?

[alastair_leith]

I have a block defined in my drawing which I wish to delete (calling it OLD_BLOCK for this Q).  

• It's a user defined block as far as I know (FAIK), as I created it inside the drawing using the a BLOCK command.
• It has a really similar name to a new BLOCK (calling it NEW_BLOCK) that I since created to replace all instances of OLD_BLOCK (yes I should have just edited the OLD_BLOCK but I didn't)
• I have deleted all instances of it in the drawing (FAIK)
• I did a purge
• now I want get rid of the listing and all reference to this block so I don't have to parse two similar names ad chose the correct one.
  
  

I can't find any reference in Documentation to deleting a block definition. 

I can't use the BLOCK text command, it insists on opening the semi-GUI dialogue box for defining a new block. I tried _BLOCK but it still opens the same modal window.

Right clicking the OLD_BLOCK listing in the Blocks palette doesn't let me delete its nor do any palette menu options.

this is one of the annoying things about the semi-GUI sub-par-GUI-standards of Autocad for Mac 2024. Should be a right click and a palette menu option to delete something in a palette listing, like always it standard in all design software I can think of, including a bunch of 3D apps.

Hi @alastair_leith ,

If you mean blocks listing on the "Blocks in current drawing" tab of the Blocks Palette, then - yes, you cannot delete unused block here.

You can remove unused block definition from the drawing only with PURGE command. If you cannot remove it, then you can check why you cannot do this on the "Non Purgeable Items" tab of the Purge window:

 >>>>I can't use the BLOCK text command,

Command line version of BLOCK command is -BLOCK

thanks. I had forgotten I'd redefined the block to contain no objects so as to avoid using the wrong block by mistake. So wasn't visible until I did a Quick select command.

the other one is referenced inside the block that replaced it. this will be more tricky to fix I expect!

When I purged I lost other blocks that I wanted to keep and are already used in the drawing… why?

Hi @alastair_leith ,

When you use PURGE command you need to check on the left side of the PURGE window only those blocks, you need to purge and uncheck "Nested items" option on the left.
