Civil 3D Files Locking Up and Crashing During Save on Panzura

Applies to: 
Civil 3D 2026 
Panzura File Systems 

Issue: 
Users experience random crashes, lockups, or long delays while saving drawings stored on Panzura. In some cases Civil 3D becomes unresponsive or closes unexpectedly. Files saved locally perform significantly better. 

Causes: 
Civil 3D 2026 has slightly different background saving procedures than earlier versions which can trip up Panzura. 

Solution: 

1 – Save the drawing locally and test performance. 

2 – Verify whether the issue occurs only on Panzura-hosted files. 

3 – Contact Panzura customer support and they can change settings to resolve the issue.
