Overview

Physna turns 3D models into searchable data using geometric deep learning. Its enterprise platform lets aerospace, automotive, manufacturing, and defense customers search, compare, and analyze large 3D model databases, identify parts in complex assemblies, and find alternatives to speed design and procurement while protecting IP. Thangs.com is a free public 3D model search engine and community where users search by geometry, share designs, and collaborate with version control and creator monetization. The company differentiates itself by treating 3D geometry as a “physical DNA” and offering both enterprise-grade search/analysis and a large user-generated 3D model ecosystem, with the goal of bridging physical objects and digital code to enable faster, safer design workflows.
