changing block names

Anonymous — Thu, 21 Sep 2017 08:31:38 GMT

Good day!

I have 100 of blocks in my dwg and the block names listed below

BLK_LT_CCT_01

BLK_LT_CCT_02

BLK_LT_CCT_03

BLK_LT_CCT_04

BLK_LT_CCT_05

BLK_LT_CCT_06

BLK_LT_CCT_07

BLK_LT_CCT_08

And so on.

Is it possible to select all of those blocks and change the block name into BLK_LT_CCT_001 only?

Is there a LISP or fastest way to solve this?.

Thanks .

Ram,

If they are all different blocks, why would you want to have them all as one block?

It is not possible, as far as I know to rename multiple blocks to one name.

The rename command fails to do so (see attached) because it wants each

separate block renamed to have a different name.

You can create a new block with all of them as nested blocks,

so that when you explode the new block, all the nested blocks are now present

as blocks in their own right.

Hi,

>> Is it possible to select all of those blocks and change the block name into BLK_LT_CCT_001 only? <<

i would like to say the follow :

there is NO need to select all blocks (as you said) for renaming procedure.
blocks MUST have their own specified names.
since you have 100 block then you will have 100 block name.

if you tell us what you want to achieve you may found more suitable solutions.

Regards,

If by "chang[ing] the block name" you mean you want to replace all those similarly-named Blocks with equivalent insertions of just the one Block named BLK_LT_CCT_001, you can use BlockReplace.lsp [attached]. Use its BRS command [which stands for Block Replace, Selected], and when it asks for:

Block to Replace existing Block(s) with <it will offer Insert's default if any>:

give it BLK_LT_CCT_001, and when it says:

To replace Block insertion(s) with BLK_LT_CCT_001,
Select objects:

give it (ssget "_X" '((2 . "BLK_LT_CCT_*")))

to find all Block insertions whose names start that way. It will replace them all, keeping each one's Layer, insertion point, scale factor(s), rotation, etc., and just changing them to be insertions of the BLK_LT_CCT_001 Block instead.
