Trimble - Transforming the way the world works.

On Monday, April 24, 2017, the anti-virus software Webroot incorrectly flagged many safe files as unsafe and had quarantined them. Several programs, including Accubid products were affected. To correct the issue, please follow the instructions here.


The following viewers are available for DuctDesigner 3D® and PipeDesigner 3D® which allow client computers to view DuctDesigner 3D and PipeDesigner 3D models. To download a file or view a PDF, click on the file name. To view PDF documents, you may require a PDF reader; Adobe Reader is available free, for download.

Important: Do not install your Trimble CAD software and the Viewer software on the same computer. Doing so will cause conflicts within the Trimble CAD program.
