ATTREDEF (Command)

Redefines a block and updates associated attributes.

New attributes assigned to existing block references use their default values. Old attributes in the new block definition retain their old values. Any old attributes that are not included in the new block definition are deleted.

Note: ATTREDEF removes any format or property changes made with the ATTEDIT or EATTEDIT commands. It also deletes any extended data associated with the block, and might affect dynamic blocks and blocks created by third-party applications.

The following prompts are displayed.

Name of block you wish to define
Specifies the name of the block whose definition you are modifying.
Objects for new block
Specifies the objects to be included in the new block definition. Select the objects.
Insertion base point for new block
Specify the location of the block base point.
