Why Convert IGES to 3DM?
IGES (Initial Graphics Exchange Specification) is a legacy CAD exchange format for engineering data. While powerful in its native ecosystem, IGES files may not be directly compatible with software that requires 3DM format.
3DM (Rhinoceros 3D) is a Rhinoceros NURBS modeling format for industrial design, jewelry, and architecture. Converting to 3DM enables seamless integration with Rhinoceros 3D (Rhino) for NURBS-based industrial design, jewelry modeling, and parametric architecture.
Our converter handles the entire process online — no desktop software, plugins, or expensive licenses required.
