What is the default username and password to access the DuctDesigner 3D software?

The default username and password can be found in the Trimble DuctDesigner 3D Installation Guide.

  • A hard copy of the guide was provided to you at the time or purchase. If you cannot locate this document, it is available from the Windows Start menu. Navigate to Trimble DuctDesigner 3D / Documentation.
  • The Installation Guide is also available on the installation media in the Help folder.
