The world’s leading solution for converting native 3D CAD data into rich 3D PDF documents.

Sharing your design with non-CAD users or those without a seat of CAD software is often difficult.

Tetra4D Converter is the world’s leading solution for converting native 3D CAD data into interactive 3D PDF documents that can be shared with anyone.

Note: Tetra4D Reviewer is included FREE with Tetra4D Converter and Tetra4D Enrich. Reviewer is a standalone x64bit native CAD viewer, mock-up tool, and translator. Learn More.

Why this is important:
With Tetra4D Converter you can share your 3D CAD data, controlling what data is included such as precise solid geometry, PMI/views and meta-data, in a highly compressed viewable format. And because Adobe Reader is installed on 98% of desktops worldwide, anyone needing to view your 3D data already has all the software they need.

  • Convert CATIA®, PTC® Creo, Pro/E, NX™, Solid Edge®, SolidWorks®, Autodesk® Inventor®, Autodesk AutoCAD® and other major CAD formats to 3D PDF
  • Includes 3D PDF conversion to neutral formats such as, STEP, JT, Parasolid, 3MF, IGES and JT
  • Control whether recipients of your 3D PDFs can measure, section, comment on or export 3D data with Adobe’s powerful security features

 Uses: 3D CAD viewing and sharing, collaboration, design review, product presentations, CAD data translation
