YourCad.Guru can help you with exporting 3D PDFs. YCG has been working with Autodesk providing feedback and improvements, and ideas since the 3D PDF was in BETA. We also presented some of the features in a brief overview at Autodesk University in 2016, 2017, 2018 and 2019 in our “Back to Basics” class. If you would like to learn more, please reach out and ask for a demo.
