If you modify or replace an AutoCAD block, you may find the attribute definitions are not updated.
In this example below, I need to add an attribute to the room tag block. I opened the block in block editor, add another attribute then save the block.
However, after you save the block you see the block is not updated. You don’t see your new attribute.
If you modify block attributes, you need to synchronize the attribute. You will not see the updated attributes until you sync it.
The block attribute modification includes:
- Adding new attributes.
- Deleting existing attributes.
- Moving the attribute and other attribute modification.
Synchronizing the attributes
To sync the attributes, you can use ATTSYNC command. You can type the command or access it from ribbon> Home tab> Block panel. Expand the block panel to see the command.

ATTSYNC allow you to select individual block to sync, or you can type block name to update all block with defined name.
After you sync the block attributes, you will see the updated attributes in your blocks.
