3D InterOp
3D InterOp is a paid software development toolkit for translating visualization data, exact B-rep geometry, and metadata between CAD formats.
What 3D InterOp is
3D InterOp is a paid software development toolkit for translating visualization data, exact B-rep geometry, and metadata between CAD formats. Its SDK reads and writes more than 30 CAD, BIM, mesh, and visualization formats. Developers can selectively import product structure, tessellated or exact geometry, and manufacturing information. Automated healing, stitching, and resurfacing can create topologically valid solid models for later workflows. The toolkit supports stable CAD topological identifiers and graphical or semantic PMI with geometric associativity. Through the CGM kernel and native APIs, it reads and writes CATPart and CATProduct and reads CATIA and SolidWorks metadata without a CAD license. It supports ACIS, CGM, and Parasolid modelers for CAD/CAM exchange, plus multithreaded and multiprocess importing. Spatial lists Windows, Linux, macOS, API, self-hosted, and cloud deployment. Pricing is on request; a free evaluation includes a discovery call, SDK, and weekly advice.
