Civil 3D Labels Displaying "Label Contains Broken Reference"

Nick Turner

Applies to: 
Civil 3D 2023, 2024, 2025, 2026 

Issue: 
Civil 3D labels that previously displayed correctly now show the message: 

"Label Contains Broken Reference" 

The affected labels may appear blank, display question marks, or lose their reference information. 

 

Causes: 

  • Referenced object was deleted 

  • Data Shortcut reference is broken 

  • Surface, alignment, or profile was renamed 

  • Object was copied between drawings 

  • Reference synchronization failed 

Solution: 

1 – Open Toolspace > Prospector. 

2 – Verify the referenced object still exists. 

3 – Synchronize any Data Shortcuts referenced by the drawing. 

4 – Use AUDIT and fix any reported errors. 

5 – Select the affected labels and review the Label Properties to identify the missing reference. 

6 – If necessary, delete and recreate the labels using the current object. 

7 – Save, close, and reopen the drawing to verify the labels update correctly.
