Have you ever wanted to go through all your drawings and ERASE a particular block... maybe it was a bad title-block, or a bad company logo, or you just don't need a date/time stamp anymore.
Well, here is a handy lisp file that works excellently with Hurricane.
http://www.74mph.com/lisp/delblk.zip
When you run DELBLK from the command line, then just give it the name of the block you want to blow-away. It will go through and ERASE all instances of it (very quickly too)
<i>If you want delete a block, but don't know WHAT the name of the block is, then just select the block and type "LIST", there you should get your AutoCAD "Text Window", or scrollback buffer. And the contents should look something like this...</i>
Command: LIST
1 found
BLOCK REFERENCE Layer: 0
Space: Model space
Handle = 80C
DEMOBLOCK1 <i><-- This is the block name !!</i>
at point, X= 0.0000 Y= 0.0000 Z= 0.0000
X scale factor 1.0000
Y scale factor 1.0000
rotation angle 0
Z scale factor 1.0000
From this example, the block is called DEMOBLOCK1, so this is what you would type at the DELBLK prompt when asked for the block name.
So here is an example you can cut and paste into Hurricane using DEMOBLOCK1 above... (of course you would change the name from DEMOBLOCK1 to whatever your block name is!)
<font face='Courier New'>;BEGIN SCRIPT
(LOAD "DELBLK.LSP") <i>(assuming delblk.lsp is in your AutoCAD path)</i>
DELBLK
DEMOBLOCK1
;END</font id='Courier New'>
And say goodbye to DEMOBLOCK1... As simple as that...
<i>NOTE: You might want to follow this script-up with a PURGE script to make sure the sucker is out of your drawing for good.</i>
Hope this helps!!
Regards,
Bill |

Bill,
I'm under the gun, and can't take time to check this out, but I've got this lisp routine that deletes "nul" blocks. I'm not sure if that is the same as "empty" blocks or not. Also not sure if it does nested blocks.
I thought I'd post it in case you had time to run a test and see if it might be of use here. (It originally did nul text/mtext also, but I commented that out so as not to remove more than is intended here.)

| I'm sorry !! The file needs to be renamed from .zip to .lsp. The forum's security doesn't like .lsp files outright. "Delnulblks" will run the lisp after it is renamed. Be sure to check it out on test files, though !! |

i think you removed the deleting part from the lsp.
it found the block and says it needs purging but it didnt delete it. |

I didn't write the lisp so I'm not certain, but I think it looked like it should have erased the block, but probably did not purge it. I've modified the attached file a little, hoping that the mods would purge the blocks, also. If it does not do that for you as furnished here, I don't think I will be able to do much more with it. It would be great to hear in a few minutes that it worked for you, though ! Good luck !!
