3D PDF Meets Berlin

3D PDF has proven to be a powerful tool for communicating engineering data. It is a unique document format that can seamlessly combine model, drawing and business data together into a single, highly compressed document that can be shared with virtually anyone.

The goal of this workshop is to introduce participants to the 3D PDF format, to show how it can be used in mechanical and architectural workflows and how it can be applied in advanced research projects.

Here, the question and answers as discussed during the workshop on May 15th 2017:

Question 1: Unfortunately, the built-in PDF viewers for Chrome, Firefox etc. cannot visualize the 3D content of a PDF. How can I force the browser to open a link to a 3D PDF document in the external Adobe Reader?
Answer 1: First, you should make sure that Adobe Reader is the default application handling PDFs. Second, in the HTML document you should use the HTML5 download attribute:

<a download="quot.pdf" href="../doc/quot.pdf">Click here to Download quotation</a>

This has been applied in the following link: Click here to download 3D-PDF document

Question 2: Is there any direct export to 3D PDF available for Cinema 4D?
Answer 2: No.

Question 3: How can I use 3D PDF in virtual reality? Is there any possibility, to visualize the 3D PDF documents in VR glasses for mobile devices?
Answer 3: Only using tricks, when captuing the output of the graphics card.

Question 4: Can different views as well as animations be exported from 3D CAD?
Answer 4: It depends on the exporter of the 3D CAD system. The Tetra4D converter enables animations.

Question 5: Is the Adobe Reader application sufficient to view 3D PDFs?
Answer 5: Yes, for Windows, Linux and Mac OS X the Adobe Reader is sufficient. Please use the latest version available, as explained under https://www.linkedin.com/pulse/yes-version-matters-phil-spreier. On Android and iOS mobile devices Tech Soft 3D’s free 3D PDF reader is available.

Question 6: Who offers PRC libraries apart from Tetra/HOOPS and PDF3D? Are there any open implementations available?
Answer 6: As open source implementation (LGPL) only the PRC writer of the asymptote project is available under: https://github.com/vectorgraphics/asymptote/tree/master/prc

Question 7: How can I export 3D PDFs from Siemens PLM NX?
Answer 7: The NX standard product does not contain a 3D PDF exporter. There is a 3D PDF exporter addon available from Theorem Solutions.

Question 8: How does 3D PDF differ from JT? What are appropriate use cases for either format?
Answer 8: Please refer to the discussion under http://www.3dcadworld.com/should-you-use-jt-or-3d-pdf/.

Question 9: Is it possible to modify the geometry stored within 3D PDFs?
Answer 9: No.

Question 10: Is it possible to protect the content of 3D PDFs?
Answer 10: Please refer to http://www.theorem.com/3dpdf/3dpdf-faq.htm#5.

Question 11: Will 3D PDF documents containing hundreds of components suffer from performance problems? Are there any tricks and tips known to deal with performance issues?
Answer 11: Depending on the display quality 3D PDFs may contain 20 – 50 thousand components. When reaching higher numbers of components, the main problem will be the graphics performance.
Do not place a large number of components on the 1st hierarchy level, as this may result in performance problems.
