3DM Rhinoceros 3D (3DM) File Format

The 3DM file format is the native format for Rhinoceros 3D (Rhino), a leading NURBS-based 3D modeling software used across industries like architecture, engineering, and industrial design. 3DM files accurately store mathematical representations of curves, surfaces, solids, and meshes, making them essential for precision 3D modeling and CAD workflows.

Key Features of 3DM Files

  • NURBS Geometry: Supports precise, smooth surfaces critical for advanced design and engineering projects.
  • Polygonal Meshes: Stores tessellated 3D models ideal for rendering, simulation, and 3D printing workflows.
  • SubD Surfaces: Allows flexible, editable subdivision modeling for organic shapes and complex surfaces.
  • Instance References: Saves memory by creating linked object instances, optimizing large and detailed models.

Convert 3DM Files Seamlessly

Autoconverter and Autoshaper simplify 3DM file conversion to popular formats like STEP, IGES, OBJ, STL, and DWG. Automate the export of 3DM polygon meshes for 3D printing, or preserve NURBS data for engineering-grade CAD models. Save files in legacy (Rhino 2.X - 7.X) or latest Rhino 8.X formats to ensure compatibility across all project environments.


IV Inventor File

The IV format is a 3D graphics file standard developed by Silicon Graphics (SGI) for representing complete 3D scenes. As a text-based format, it stores hierarchical scene graphs containing geometric shapes, materials, lighting, textures, and environment properties. Closely tied to the Open Inventor toolkit, this format served as a foundational C++ library for 1990s 3D graphics development.

Key Features of IV

  • File Structure: Uses human-readable ASCII encoding with nested node hierarchies that organize 3D scene elements.
  • Format Origin: Developed by Silicon Graphics in the early 1990s as the native file format for their Open Inventor 3D graphics toolkit.
  • Scene Representation: Implements a directed acyclic graph (DAG) structure to define parent-child relationships between 3D objects.
  • Visual Attributes: Stores comprehensive material definitions including ambient/diffuse/specular colors, shininess, and transparency.
  • Texture Mapping: Supports both procedural and image-based textures with UV coordinate mapping.

IV File Conversion

Autoconverter simplifies the process of converting your 3D models into the IV format, ensuring seamless compatibility with both legacy and modern 3D tools. Our IV files converter preserves your geometry, materials, and scene hierarchy in a human-readable structure that remains editable across workflows. Still using legacy Open Inventor tools?
