Removing nested block from main block

[lgabriel]

I get an AutoCAD drawing from my conveyor manufacturer who have buried a block (tagname) in all of their conveyor blocks.

The only way to remove them is to manually use BEDIT and erase the tagname block. Very time consuming

Is there a way through Autolisp to search all blocks in a drawings and if the tagname block is part of the definition of the conveyor block, erase the tagname block or redefine the conveyor block without the tagname block.

Try my Extract Nested Block program.

How about just re-defining the "tagname" block into something inconsequential, like a node (point) or a small circle on a noplot layer?

Just delete everything from "tagname" in BEDIT.

Alternatively, my Delete Blocks program will delete all references of one or more blocks from a drawing.

To all above suggestions, thank you for your responses. The DELBLOCKS.lsp does exactly what I need.

Excellent - you're welcome!

The reason I wouldn't do that is that I don't like the idea of having a block definition in the dwg that cannot be easily "found".  (It's probably just me, though. )

I marked Lee's suggestion as the solution if you don't mind.

This lisp routine did exactly what I was hoping. Thank you so much!

Perfect for a file with 300 blocks nested in 300 other blocks! saved me a lot of time. 10/10 would recommend
