Theorem’s Publish 3D helps to protect design and visualization IP using 3D PDF

Our latest Publish 3D3D PDF suite of products now offer greater levels of Intellectual Property (IP) protection  to users publishing 3D CAD data directly to a PDF document from within their design and visualization applications.

PDF files containing interactive 3D data created using our Publish 3D provide a higher level of Intellectually Property (IP) security than native CAD files by allowing the documents to be password protected.

Native CAD files cannot be password protected, causing IP vulnerabilities when shared or accessed. 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
  • Data Rights Management added
  • Restricted access for specific users with other applications such as LiveCycle, FileOpen etc.


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.

3D PDF is opening up opportunities for securely sharing information within an organisation and up and down the supply/distribution chains, allowing improvements to assembly, reducing product cost and improving quality.

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.

The simplicity of 3D PDF, low cost, and ease of use allows for the secure integration of departments, customers and suppliers into the product lifecycle process which in turn leads to reduced lead times, fewer mistakes and better products.
