Frequently Asked Questions

How do I restore deleted blocks in AutoCAD?
Once blocks are purged in AutoCAD, they are permanently removed from the drawing. To restore a deleted block, you would need to reinsert it from a block library or redraw it manually.

What happens if I delete a block used in multiple instances?
Deleting a block that is used in multiple locations within your drawing will remove all instances of that block. Ensure you have a backup or no longer need those instances before purging.

Can I delete blocks in AutoCAD without using the command line?
Yes, you can delete blocks using the Properties palette. Select the block you want to remove, open the Properties window, and choose the option to delete the block through the UI. However, this method may not allow you to purge unused blocks like the PURGE command does.
