3D CAD IP protected within PDF files

By Julien Happich

Using 3D PDF, the CAD data can be translated into a tessellated format, with content such as features, history and constraints being removed, so that the 3D representation can be viewed and manipulated, but the native CAD data cannot be accessed or reproduced from the PDF alone.

This added functionality gives greater confidence when sharing sensitive information with partners and suppliers. Using standard Adobe PDF security, a 3D PDF can be password protected, encrypted with restricted access for specific users with other applications such as LiveCycle, FileOpen etc. Data Rights Management can also be added.

A 3D PDF has the capability for the document to be annotated, and can also act as a ‘carrier’ file for additional data to be transported (such as spreadsheets, AVI Movies, hyperlinks, as well as native CAD data) and create a richer file and source of information, but still keep IP secure.

Anybody with access to the freely available Adobe reader, either on a PC, tablet or phone can access interactive 3D data and are able to view, mark up and interrogate the data without the use of specialist CAD software.
