Replace Selected Block Or Blocks With Another Block

DOES ANYONE HAVE A QUICK AND EASY WAY TO REPLACE A SELECTED BLOCK. ALSO IS THERE A WAY TO REPLACE MULTIPLE SLECTED BLOCKS AND REPLACE WITH A DIFFERENT BLOCK TYPICAL FOR ALL THE BLOCKS THAT ARE SELECTED? I HAVE A BIG A$$ PROJECT DUE FRIDAY AND NEED TO SWAP OUT ALOT OF BLOCKS NOW...

Ouch... not so loud

Have you tried the Express Tools' Blockreplace?

LOL sorry about that. Yes, I have express tools. The Blockreplace command replaces all the blocks i just want to replace the block that I have manually selected. I pulled an old stript and trying to alter it but not sure if I can pull it off though.

nope couldn't get the script to work I am a not good at writing or modifying lisp my bock i need to replace is smoke 1 with smoke rb

try Bre.lsp from Alan Thompson... It's works quite well..

See updated CODE

I forgot all about that one. Haven't used it since the project I wrote it for.

I'm trying to run the above but get an error: "Error: no function definition: VLAX-ENAME->VLA-OBJECT"

Some of the blocks I'm selecting have spaces, dashes and underscores...could that be a problem?

add (vl-load-com) to the code

Recopy the code, I added (vl-load-com).

Perfecto!!!!!!!!

You're so awesome. This is awesome. You're a life saver.

Can't thank you enough.

Hi Alan J,

I've been searching for a block replace Lisp for three days but couldn't find any good one. I found this lisp it is working nice, I wanted to ask is it possible to make this lisp a batch block replacement so that you don't need to open every drawing to change blocks. I have to replace old blocks from new blocks in more than 300 drawings.

If it is possible plz tell.

Thanks for your previous (BRE) Lisp too.

Do you have a similar routine that wors with attributes? I often have to change (blocks with attributes) parts of my drawing from proposed to existing. The blocks are the same except for color and font style. Thanks

Take a look at Lee Mac's Batch Attribute Editor.
