FAQ
1. Can I delete multiple blocks at once in AutoCAD?
Yes, by using the PURGE command, you can select multiple block types to delete at once. You can also select multiple instances of a block using the Erase command.
2. What happens if I delete a block that is used in multiple locations?
Deleting a block will remove all instances of that block from your drawing. If you only want to cease its use without removing it completely, consider editing its attributes first.
3. Are there any ways to recover a deleted block in AutoCAD?
If you delete a block and later want to restore it, you may be able to use the Undo command immediately after deletion. If you have saved your drawing after deletion, recovery may not be possible unless you have a backup.
