I just haven´t found some of these routines posted around in this Forum... So I want to post them all in this thread to show some gratitude for your constant help and support....
1. These are 5 routines.. The first one is for Block names' find and replace... and if you use "*" for "Enter Block name pattern to match:" you can find and replace a string in the entire block database in the current drawing.
2. The second one is to add a preffix or suffix to current drawing block names...
3. The third one is a vba command to replace a character from blocks names.
4. The fourth is the Block renamer... already posted by me from Theswamp.org and Lee... to rename completely all Blocks in the current drawing using a preffix (inside the lisp) and a number sequence.
5. The fifth, also recently posted... works to rename specific blocks to a completely different name... kind of fixed by me from a layer renamer lisp (also posted)
