🏆 Convert DWG to IV: AutoCAD Drawing to Open Inventor Format Converter

How to Convert DWG to IV?

Export DWG drawings to IV like a professional - our proven 3-step process delivers precise, consistent results every time:

  1. 📥 Install Automesher Application

    Download and install Automesher Application for AutoCAD, BricsCAD, GstarCAD, or ZWCAD - it adds the AmExportMesh command needed to export IV files directly from DWG drawings. Restart your CAD software after installation to load the plugin.

  2. ▶️ Run IV Export Command

    Type AmExportMesh in the command line and press Enter. Select the 3D entities you want to export from the DWG model space - supported types include Polyface Mesh, Polygon Mesh, 3D Solid, and 3D Face - then press Enter again to confirm the selection.

  3. 💾 Save as IV File

    In the save dialog, select IV (*.iv) as the output format, choose your destination folder and filename, then click Save. Automesher converts the selected DWG entities and writes them to your file.

DWG What is a DWG File? (AutoCAD 2D/3D CAD Drawing Explained)

The DWG file format is a proprietary binary format developed by Autodesk for storing 2D drawings and 3D models in CAD (Computer-Aided Design) workflows. As the native format for AutoCAD, DWG files are widely recognized as the industry standard across architecture, engineering, and construction sectors for their precision, flexibility, and cross-platform compatibility.

Key Features of DWG Files

  • Broad Compatibility: DWG files work seamlessly with popular CAD programs like AutoCAD, BricsCAD, ZWCAD, and IntelliCAD, ensuring easy sharing and collaboration across different software environments.
  • High-Precision Vector Data: DWG files store exact vector-based 2D graphics, 3D models, and rich metadata, making them ideal for detailed blueprints, architectural designs, and complex engineering projects.
  • Efficient Use of Blocks: DWG drawings support reusable "blocks" - predefined components like symbols or templates - that help streamline design workflows, ensure consistency, and reduce file sizes.

DWG File Conversion Made Simple

Looking to convert DWG files into popular 3D or GIS formats like OBJ, STL, DXF, KML, or KMZ? Our tools, Automesher Application and Automapki Application, enable fast, accurate DWG conversions while preserving design details.

IV 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.
