✨ Convert DWG to OBJ: AutoCAD Drawing to Alias-Wavefront File Conversion

How to Convert DWG to OBJ❓

Get your DWG drawings into OBJ format quickly and precisely with our simple, easy-to-follow 3-step process:

  1. 📥 Install Automesher Application

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

  2. ▶️ Run OBJ 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 OBJ Mesh File

    In the save dialog, select OBJ (*.obj) 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.

OBJ What is an OBJ File? (Alias Wavefront Object Explained)

The OBJ file format is a widely used open standard for storing and exchanging 3D geometry, originally developed by Wavefront Technologies. Unlike binary formats, OBJ files use a human-readable text format, making them highly compatible across 3D modeling, animation, and rendering software.

Key Features and Benefits of OBJ Files

  • Multiple Named Objects: OBJ files can contain multiple 3D objects within a single file, each organized with individual names, ideal for complex 3D scenes and asset management.
  • Surface Materials and Textures: OBJ files support detailed surface definitions, including transparent materials and texture mapping, enabling realistic 3D model rendering.
  • Quad and Triangle Support: Geometry in OBJ files can include both quads and triangles. During OBJ file conversion, quads are automatically divided into triangles to ensure compatibility with applications that only support triangular meshes.
  • File Size Considerations: As a text-based format, OBJ files tend to be larger than binary formats like SKP or 3DS, which can impact loading speeds and storage requirements for complex models.
