What is the BATTMAN command?

BATTMAN (Block attribute manager) is AutoCAD’s tool to manage attribute definitions inside a block definition. Use BATTMAN to:

View all attribute definitions (tags, prompts, defaults) for a specific block.
Edit attribute properties (tag name, prompt text, default value, and mode options such as Invisible, Constant, or Verify).
Rename tags or reorder attribute definitions.
Delete attribute definitions from the block definition.

Important: BATTMAN edits the attribute definitions in the block definition, not the attribute values in block instances in the drawing. After changing a definition, you usually need to sync the block references so the instances reflect the new definition.

When to use BATTMAN

Use BATTMAN when you need to:

Standardize attribute tags across blocks (e.g., change TAG1 → PART_NO).
Change the prompt or default value that appears when inserting or editing a block.
Make an attribute invisible, constant, or set it to verify.
Reorder attributes to control the attribute edit sequence during block insertion or update.

Always save a backup copy of your drawing before changing block definitions.

How to use BATTMAN — Step by step

Quick command entry

Type BATTMAN at the AutoCAD command line and press Enter.
Or use the Ribbon: Insert tab → Block Definition panel → Block Attribute Manager (label may vary by AutoCAD version).

Step-by-step workflow

Save your drawing (create a backup).
Run BATTMAN.
In the dialog, use the Block dropdown or list to select the block definition you want to edit.
The dialog displays all attribute definitions for that block. Select an attribute from the list.
Click Edit (or double-click the attribute) to change:
- Tag (attribute identifier)
- Prompt (text shown when editing or inserting)
- Default (initial value)
- Modes (check/uncheck Invisible, Constant, Verify, etc.)
To rename a tag, use the Rename or Edit function. Renaming a tag will not automatically update values in existing references until you sync.
Use Move Up/Move Down or an Order button to change the sequence of attributes.
To delete an attribute, choose Delete (ensure you really want to remove it).
Click OK or Apply to save changes to the block definition.

Synchronize block references

After modifying attribute definitions, run ATTSYNC to update existing block instances:

Type ATTSYNC at the command line.
Choose the block(s) to synchronize (you can type the block name or select from the list).
Confirm to update references. This will add new attributes to existing block instances, remove deleted attributes (values may be lost), and update tag names where possible.

Examples (before and after)

Before: Block “VALVE” has attributes TAG1, TAG2. TAG1 is named “TAG1”, prompt “Tag”.
Action: Run BATTMAN, rename TAG1 → PART_NO, change Prompt to “Part number”, set Default to “UNKNOWN”, click OK, then run ATTSYNC on block “VALVE”.
After: All block instances of “VALVE” now show PART_NO as the attribute tag; new prompt and default are applied when inserting or editing.
Before: Attribute “SIZE” appears in the wrong order during insertion.
Action: In BATTMAN, select “SIZE” and move it up or down to set the desired order, then ATTSYNC.
After: The attribute edit sequence during insert now follows the updated order.

Alternative commands and methods

ATTDEF — Create a new attribute definition. Use with BEDIT to place it inside a block definition.
BEDIT (block editor) — Edit a block definition graphically; use ATTDEF inside the Block Editor to add or position attributes.
ATTEDIT — Edit attribute values in block references (edits values of instances, not definitions).
EATTEDIT (Enhanced Attribute Editor, Express Tools or built-in in some versions) — Batch edit attribute values across many block instances.
REFEDIT — Edit an inserted block instance in place (for nested or instance-level changes).
ATTSYNC — Force block references to sync with the block definition after changes made by BATTMAN or BEDIT.
If BATTMAN is not available in your interface, open the Block Editor and manage attributes directly there.

Common problems and fixes

Problem: “Command not found” when typing BATTMAN.
- Fixes:
  - Ensure you’re using a supported AutoCAD product/version (some specialized or older versions may not include the same UI).
  - Check your workspace or Tool Palettes—try the command line entry.
  - If using AutoCAD LT and BATTMAN is not present, use BEDIT and ATTDEF as alternatives.
Problem: Changes in BATTMAN don’t reflect in block instances.
- Fix:
  - Run ATTSYNC on the affected blocks to update existing references.
  - If ATTSYNC doesn’t update, the reference may be an anonymous or dynamic block—edit via BEDIT or reinsert the block.
Problem: Block definitions come from an Xref and attributes can’t be edited.
- Fixes:
  - Open the source drawing that defines the block, edit it there, save, then reload the Xref.
  - Alternatively, bind the Xref into the host drawing (with caution) and then edit the block definition.
Problem: Attribute values are lost after deleting or renaming tags.
- Fix:
  - Always backup before deleting attributes.
  - Use ATTSYNC after renaming; if the tag name changed, AutoCAD may not preserve the previous value—plan accordingly and export attributes (with ATTEXT or data extraction) before changes if needed.
Problem: Attributes inside nested blocks or anonymous blocks are hard to manage.
- Fix:
  - Use BEDIT to open the nested block or edit anonymous block definitions. Use REFEDIT on instances when appropriate.

Tips and best practices

Always save a copy of your drawing before changing block definitions.
Use consistent tag names across your blocks to make extraction and scheduling easier.
When modifying attribute tags used by scripts or data extraction, update downstream processes.
Use ATTSYNC immediately after changing definitions to ensure consistency for all block instances.
Consider adding attributes and their positions inside the Block Editor (BEDIT) for precise control of geometry and attribute placement.
If you need to update attribute values in many instances, use EATTEDIT or export attributes to a table (ATTEXT or Data Extraction), edit externally (spreadsheet), and reimport.

FAQ

How do I update attribute values in existing block instances?

Use ATTEDIT or EATTEDIT to change attribute values in instances. After changing attribute definitions with BATTMAN, run ATTSYNC to propagate definition changes to existing instances.

Can I add a new attribute to an existing block using BATTMAN?

No—BATTMAN manages existing attribute definitions; to add an attribute, open the block in the Block Editor (BEDIT) and use ATTDEF to create and place the new attribute, then save and run ATTSYNC if necessary.

Why don’t my attribute changes show up after running ATTSYNC?

Possible reasons:

You edited a block inside an Xref; you must edit the source drawing or bind the Xref.
The block instances are anonymous or part of a dynamic configuration; edit them with BEDIT or reinsert updated blocks.
The tag name changed in a way that prevents matching of existing values—backup and export attributes before renaming.

Is BATTMAN available in AutoCAD LT?

Function availability can vary by product/version. If BATTMAN is not available in your AutoCAD LT workspace, use the Block Editor (BEDIT) with ATTDEF or manage attribute values with ATTEDIT / EATTEDIT.

How do I preserve attribute data when renaming a tag?

Best practice:

Export attribute data first (via ATTEXT or Data Extraction).
Rename tags in the block definition.
Use the exported data to remap values if they are not preserved automatically after ATTSYNC.

Can BATTMAN change attribute order for the insert sequence?

Yes—BATTMAN lets you reorder attribute definitions (Move Up/Move Down). After ordering, run ATTSYNC to ensure instances use the updated sequence at insert or edit time.

What should I do before deleting an attribute from a block?

Always backup your drawing and export attribute data if you might need it later. Deleting an attribute definition may remove values from existing block instances permanently.
