What we do

What the team develops

OCCT3D develops core geometry technology, reusable components, application software, integrations, and long-term support for 3D engineering products.

Open-source foundation

Develop and maintain a widely used C++ platform for 3D applications.

Added-value technology

Package focused capabilities that product teams can integrate without rebuilding them.

Application engineering

Turn technical capabilities into reliable workflows and coherent products.

How we work

How engineering work is reviewed

Design and implementation decisions are reviewed against representative models, documented interfaces, tests, and the requirements of the application using the technology.

The aim is a maintainable application boundary around complex geometry and product data.

Next step

Discuss an OCCT-based product or integration.

Start with the current application, a representative model, or the planned workflow.
