4. Change Attribute Settings: Within the palette, navigate to the “Misc” section. Look for the “Constant” checkbox and set it to “No.” This change allows the attribute to be edited.

5. Synchronize Changes: Utilize the ATTSYNC command to synchronize any changes made with the block. Select the block reference to ensure all updates are applied.

FAQ

1. What happens if I forget to save my changes in the Block Editor?
Failure to save will result in your modifications being lost. Always ensure to save before exiting the Block Editor.

2. Can I lock a block again after unlocking it?
Yes, you can reapply the lock on a block by returning to the Properties palette and setting the “Allow Exploding” option back to “No.”
