PolyTrans is desktop software for converting CAD, mesh, DCC, animation and 3D scene files. It is aimed at engineering, manufacturing, aerospace, animation, visualization and VR/AR workflows that need to move geometry and scene data between applications and formats. Conversion can include hierarchy, materials, textures, lights, cameras and format-specific animation data, while bidirectional animation conversion supports production pipelines beyond static model exchange.

The published plans show a $395 one-time price for PolyTrans for Windows, which includes the base conversion package and a PolyTrans-for-3ds-Max plug-in. Optional packs expand the format scope: CAD/Pack and DCC/Pack each cost $245 one time, Granite/Pack costs $395, CAD-Granite Pack and DCC-Granite Pack cost $510, CAD-DCC Pack costs $395, and Triple-Pack costs $695. These additions cover formats and integrations such as Inventor, DWF-3D, DXF/DWG, ProE/Creo, IGES, Parasolid, STEP, Maya and OpenFlight. The Triple-Pack includes the first year of vendor maintenance and royalties, while Granite/Pack includes one year of free updates and maintenance.

PolyTrans stands out when a pipeline needs both format breadth and processing controls. Batch conversion handles 3D and bitmap files, while polygon reduction and scene optimization address asset preparation. Native 3ds Max and Maya plug-ins, integrations with Cinema 4D, LightWave, Blender, Unity, Unreal Engine, SketchUp and OpenFlight, plus a 2D/3D import-export API and plug-in SDK, support varied production environments. The trade-off is a Windows-first setup: the Mac version runs through Parallels or VMware, and the functionally limited demo is not a perpetual free plan. Choose PolyTrans for complex CAD-to-DCC or animation workflows; choose another converter if native macOS operation or a free plan is essential.
