About CDK Systems
CDK Systems, based in Sophia-Antipolis, France, specializes in custom software solutions for 3D, CAD and BIM. Focus areas include robust mathematical and geometrical libraries, interoperability engines for CAD and 3D applications, and software R&D in computational geometry and model processing. Technologies developed under CDK Systems enable efficient import, translation, and optimization of CAD data, including STEP and IFC formats, ensuring seamless interoperability across industrial, architectural, and digital workflows.
CAD/BIM and 3D Software Services
CAD/BIM Interoperability
Development of converters and import/export tools for CAD files using proprietary mathematical libraries, providing consistent and unique results.
Custom 3D Applications
Development of desktop 3D applications in high-performance C/C++, including viewers, modeling, visualization tools, and custom 3D workflows.
Mathematical CAD Libraries
Robust geometric libraries for BREP, NURBS, booleans, tessellation, intersections, and topology. All code is handcrafted — no AI-generated code is used.
Some reference models used for interoperability testing are provided by NIST. Used without restriction. No endorsement by NIST is implied.
