3DPDF Converter for Revit® LTV

"3D PDF Converter for Revit® LTV is an integrated software working within the Revit® environment that enables users to publish rich, interactive, 3D PDF files that are significantly smaller than the original Revit® 3D models. The software uses the 3DA Technology as a one button file conversion that is easily exchangeable and viewed with the free Adobe Reader. ( The converter does not require Adobe XI Pro to create 3D PDF’s)

"The 3D PDF Converter for Revit® LT Visualization connects the extensive Building Information Modeling (BIM) community for the first time with a Revit plug-in that supports data sharing using 3D PDF based on the PRC file format. The software uses the same native 3D technology used by Adobe to create and consume 3D PDF files, ensuring that data generated from Revit design has guaranteed compatibility to Adobe Acrobat and Adobe Reader. The result is accurate, data-rich 3D models that are up to 97% smaller than the original Revit file."

There's a 15-day free trial of this add-in available on the Autodesk Exchange | Apps website.
