CPIXML Extension for Civil 3D 2020

The Autodesk Civil 3D CPIXML Exporter allows a Civil 3D Model to be exported to the CPIXML file format to be used by external applications for 4D BIM, 5D BIM and coordination processes. In addition to the model hierarchy, the geometries elements and the predefined and user defined property sets can be exported.

The Export CPIXML Command was added to the Civil 3D Toolbox under Subscription Extension Manager. There is no longer a ribbon entry for the command.
