Remove Block Attributes
You can remove attributes from block definitions and from all existing block
references in the current drawing. Attributes removed from existing block
references do not disappear in the drawing area until you regenerate the
drawing using REGEN.
You cannot remove all attributes from a block; at least one attribute must
remain. If you need to remove all attributes, redefine the block.
Update Block References
You can update attributes in all block references in the current drawing with
changes you made to the block definition. For example, you may have used
the Block Attribute Manager to modify attribute properties in several block
definitions in your drawing but elected not to automatically update existing
block references when you made the changes. Now that you are satisfied with
the attribute changes you made, you can apply those changes to all blocks in
the current drawing.
You can also use ATTSYNC to update attribute properties in block references
to match their block definition, or to update a block instance after you redefine
a block attribute using BLOCK, -BLOCK, or BEDIT.
Updating attribute properties in block references does not affect any values
that have been assigned to those attributes.
Edit Attributes in a Block Reference
You can select an attribute in a block reference and use the Properties Inspector
palette to change its properties, or you can use the Enhanced Attribute Editor
to modify all the attributes in a selected block reference.

Disassemble a Block Reference (Explode)
If you need to modify one or more objects within a block separately, you can
disassemble, or explode, the block reference into its component objects.
