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 File - Open Inventor 3D Scene Format
The IV file format, also known as the Open Inventor format, is a text-based 3D graphics standard originally developed by Silicon Graphics (SGI). Designed for complete 3D scene representation, IV files use hierarchical scene graphs to define geometry, lighting, materials, and textures. The format played a key role in early 3D development and is tightly integrated with the Open Inventor API - an object-oriented C++ toolkit used in scientific visualization, CAD, and simulation.
Key Features of IV Files
- Readable File Structure: Human-friendly ASCII format that organizes 3D content using nested nodes for easier editing and scripting.
- Scene Graph Hierarchy: Defines parent-child relationships between 3D objects using a directed acyclic graph (DAG) structure.
- Rich Visual Metadata: Includes lighting, shading, camera settings, and full material definitions (specular, ambient, diffuse, transparency).
- Texture Support: Handles both procedural and raster-based textures using UV mapping coordinates.
- Legacy Compatibility: Ideal for scientific and engineering applications that still rely on Open Inventor-based platforms.
Convert IV Files to FBX, glTF, OBJ, and More
Use Autoconverter to easily convert IV files to modern 3D formats like FBX, glTF, STL, OBJ, and DAE. Our IV file converter preserves full scene structure, materials, and geometry, bridging the gap between legacy and modern 3D workflows. Whether you are updating legacy data or working in cross-platform 3D environments, Autoconverter makes IV file conversion seamless and reliable.
