Cadster 3D Converter Core vs Convertpoly

Cadster 3D Converter Core is cloud-ready conversion software for engineering teams handling CAD, BIM, mesh, point-cloud, and other 3D files. A single input can produce one output format or several in one workflow. Listed inputs include IFC, STEP, IGES, BREP, 3DM, STL, OBJ, FBX, glTF, and GLB; outputs include OBJ, PLY, GLB, glTF, STEP, IGES, IFC, STL, FBX, and PDF, among others. Standard mode keeps the model’s original geometry and structure. Instanced mode targets repeated components and can reduce file size where supported. Cadster describes uses in CAD and BIM coordination, manufacturing, prototyping, digital twins, visualization, and browser viewers. Users can upload files through a browser, choose an output, and run conversion. API access is offered through a 30-day license with payment and license validation. Early renewal preserves remaining paid days, and the same API key remains usable while active. Basic is free; Pro, Full, and the Converter License have no listed prices.
