3D PDF Is Not Activated in Firefox

Clicking a CAD image in a converted 3D PDF file activates the ability to manipulate the CAD content interactively. If this feature is not available in a 3D PDF file opened in Firefox, this file may be loaded without using Adobe Reader.

The following process outlines the solution to configure Firefox to load PDF files using Adobe Reader:

1. Open Mozilla Firefox.
2. Go to Settings and select General
3. Click Applications.
4. Set the Portable Document Format (PDF) Content Type to the Use Adobe Acrobat Reader (default) Action.
