Issue:

After modifying referenced objects, redefining blocks, or copying content across drawings, FIELD values may:

  • fail to update
  • display outdated values
  • show "####"
  • lose object association
  • become static text unexpectedly

Causes:

  • FIELD references rely on ObjectID associations.
  • FIELD update timing depends on regeneration settings.
  • Attribute FIELDs inside blocks may require synchronization.
  • ####display usually indicates evaluation failure.

Solution1: 

  1. Update field by UPDATE or REGEN command.

  2. Ensure automatic field updates are enabled.
    Check:
    OPTIONS → User Preferences → Field Update Settings → Auto update field → Apply & Close

  3. If field is inside attributed blocks:

    • Use BATTMAN to open the Block Attribute Manager dialog.

      In the dialog box, specify the Block name→Sync→ok.
    • Or we can execute ATTSYNC command to to synchronize existing block references.


Solution2: 

If Solution 1 does not work after cross-drawing operations, block redefinition, or object replacement, the original field association may already be broken.

In this case, it is recommended to recreate the field association based on the original object geometry.

  1. Open the original drawing and identify:

    the original referenced geometry
    the Object type and referenced Property


  2. Copy both the original geometry object and the corresponding field object to the target drawing.

  3. If the field still cannot update correctly, redefine the field manually:

    • Run ATTDEF
    • Go to:
      Define Attribute → Tag → Turn to Defaut tab and click Field button → Specify Field category by Object → Specify Field name by Object → click Object type button

  4. Select the required object property(for example: End point, etc.)
    Configure the field format as required → Click Ok → Click Define and Exit.

  5. Finish the ATTDEF definition and recreate the attributed block.
    After rebuilding the field association, the field value should update and display correctly again.
