AutoCAD - Bulk Block Rename

[Seychellian]

Hi I searched google for this and couldnt find a solution.

I am shifting a block library to a new company name and I need add a prefix to all the blocks (1000's) to differentiate them. I know you can rename blocks with the RENAME command in AutoCAD but how can i bulk rename them to avoid the laborious task of doing each one individually?

Thanks!

You would need some LISP that renames all necessary blocks in one file - without failure. Use can use THIS one for example, but you can find plenty of others.

Then you would need a SCRIPT PRO HERE to apply the lisp across the files...

• Blocks as separated dwgs in directories, you need a software as the lovely Ant Renamer
• Blocks recorded in a drawing ? You could list them or do you have a computated list of names already ? In such case, Excel and a script built with is a natural and easy solution. Try the command -RENAME (not RENAME), it shows you that it can be done with script. But you need a list of precise names in order not to fail. Or you need a lisp that test each name, in case.

If all blocks are in current drawing, you can use wildcard to rename all of them in one go.

Well done @3wood because, yes, wild-car is allowed..., i forgot that !

[Just be aware that the * wildcard approach in RENAME works only to add a PREFIX to all Block names.  You can't add a SUFFIX to all of them that way.  That's enough for the OP's request, but there is that limitation.]

and here we talking about PREfix 😊

Suffix is also possible, but only by one step for blocks with the same name length.

I you have blocknames, all with the same length, one step for all blocks.

This is EXACTLY what im looking for. It's very rare that happens.

Thanks a lot. Youre a life saver!
