An Attribute definition can be deleted by removing the corresponding entry on the Attribute Definitions dialog. When an Attribute definition is deleted, all values that have been assigned for that Attribute (for any design element) will also be removed from the design.
Because this Attribute deletion is irreversible, it should be done with caution.
All Attribute definitions can also be removed from a design using an operation in the Design menu.
