inserting multiple blocks

Does anyone know of a lisp routine to insert multiple blocks.
I need to insert 8 blocks into over 100 drawings.
I need to determine the following:
1. determine if the block exists
if no insert block
if yes redefine it
Any help would be greatly appreciated.

 

You can always use INSERT block_name=block_name in your routine.

It doesn't matter weather the block has bee defined or not. -David

 

If the objective is to 'update' or 'replace' blocks with similar / updated blocks..then I have found it useful to search the drawings for 'old' blockname, if found, rename it _oldblockname, get it's insertion point, delete it, insert the 'new' block at the same insertion point, loop. When done, do a couple of (command "_purge" "b" "n" "") lines just to cleanup. A single Lisp can be loaded for each drawing, do it's thing, and qsave, next in a script.

I have a lisp that sets up a script file for processing all .dwgs in a
folder, including subfolders.

If that would be useful I could send it to you.
