We’re Leaders In Our Industry

The Tetra4D® brand evolved out of a collaboration between independent software developers and Tech Soft 3D, the exclusive Adobe® partner responsible for delivering 3D technologies to Adobe OEM developers. The Tetra4D brand is now wholly owned by Tech Soft 3D, and Tetra4D products are offered alongside the company’s complementary HOOPS product lines. While Tech Soft 3D makes the 3D PDF format available to software vendors through the HOOPS SDKs, the Tetra4D end-user products are sold through resellers, and via a dedicated eStore. The Tetra4D brand continues to build off of the organizational strength, technical innovation and market expertise that have characterized Tech Soft 3D since its founding in 1996.


Tech Soft 3D is the creator of the PRC format, which is part of the PDF standard. PRC is the format used at Tech Soft 3D in the HOOPS Publish 3D PDF publishing toolkit, and is also supplied to Adobe for use in Adobe Acrobat® and Adobe Reader®.

We are proud to be an Adobe Gold Technology Partner, leading the market as a provider of 3D PDF technology solutions for Adobe Acrobat. By providing rapid ongoing delivery of new 3D PDF products to the market, Tech Soft 3D helps grow the thriving ecosystem of users around the globe who depend on 3D PDF for sharing their valuable 3D data with anyone, anywhere, using the free and ubiquitous Adobe Reader.

Tech Soft 3D is a global company headquartered in Bend, Oregon. We have sales offices in England and Japan with development sites in Lyon, France and Berkeley, California.
