What CAD Exchanger is

CAD Exchanger is a set of tools for viewing, converting, analyzing, and working with 3D CAD data. CAD Exchanger Lab exchanges data in more than 30 CAD and BIM formats. It can inspect assembly structure, geometry, properties, and PMI; measure models; create sectioned or exploded views; and edit models. Its SDK offers C++, Python, C#, Java, and JavaScript libraries for adding CAD and BIM data access to web, server, or desktop applications. It supports integrations with Unity, Three.js, UNIGINE, Parasolid, Open CASCADE, C3D, ACIS, and Rhino/OpenNURBS, and uses parallel computing for tasks such as import, export, healing, meshing, visualization, and simplification. Lab is available through subscription or perpetual licensing, with node-locked or floating options. Floating licenses require a license server in the user's environment and limit simultaneous use to the number purchased. Lab subscriptions stop working when their term ends; perpetual licenses continue after maintenance lapses but no longer receive new releases. A free evaluation trial is available by request. Pricing is on request.

Who it suits

CAD Exchanger suits people who need to inspect or edit CAD and BIM models, and developers building web, backend, or engineering applications that access this data. The SDK is also described for 3D web, AR/VR, Unity, and manufacturing-as-a-service applications.
