Question
How can I delete the blocks that I created and no longer need them? I want to clear up all old blocks to start a new block list.
I have tried to used the command "purge" but it didn't work. The help file has no use to address this option. I am using AutoCAD 2008 at school.
Please help. Thanks in advance.

Answer
I assume you have already tried the PURGEALL command. There is no easy way to clean this with lisp. If the purge command won't get rid of the blocks then they are still inserted in your drawing somehow, most likely inside a nested block. Check the other blocks you still have inserted for a nested block.
Blocks are drawings unto themselves. They can contain all of the information that an entire drawing contains. So if you have references left around, they could even be unused (uninserted) blocks inside another block. Until the "parent" insert gets erased or exploded, the "children" will not purge.
Perhaps the best way might be to start a clean drawing and copy what you want over to it in pieces and keep an eye on the block list in the new drawing for the unwanted blocks to show up, this could lead you to the culprit.
