Instead of HOOPS Exchange
HOOPS Exchange alternatives
HOOPS Exchange is built for development teams that need to bring 2D and 3D CAD import and export into engineering applications through a C++ SDK. It exposes data such as B-REP, PMI, model trees, views, persistent IDs, styles, and visualization data, and works across a broad set of CAD formats. Its integrations include geometry kernels and visualization technologies, while PRC support is intended to preserve data integrity and geometry accuracy. A free evaluation provides full access for 60 days, but its license cannot be used in production, so continued use requires paid licensing.

An alternative may suit you better if you need a free standalone converter, a focused format workflow, or a different way to process models. HOOPS Exchange covers desktop, web, and mobile platforms, though its FAQ describes limited functionality on iOS and Android. Upgrades also require recompiling applications because releases are not binary compatible with older versions. Compare whether you need CAD structure and broad import/export, or instead mesh conversion, local browser processing, batch command-line work, or a desktop viewer. Check output formats, commercial-use terms, animation needs, and development interfaces before switching.
