How to Convert DWG to OFF?
From DWG drawings to OFF format in just 3 steps - fast, accurate, and beginner-friendly:
📥 Install Automesher Application
Download and install Automesher Application for AutoCAD, BricsCAD, GstarCAD, or ZWCAD - it adds the AmExportMesh command needed to export OFF mesh files directly from DWG drawings. Restart your CAD software after installation to load the plugin.
▶️ Run OFF 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.
💾 Save as OFF Mesh File
In the save dialog, select OFF (*.off) 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.
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

OFF File Format - 3D Object File for Polygon Meshes
The OFF (Object File Format) is a simple, ASCII-based 3D file format used for representing polygonal geometry in a lightweight, non-proprietary structure. Designed for academic and development use, the OFF format efficiently stores 3D model data using only vertices, faces, and optional edge information - ideal for geometry-focused workflows without material or texture metadata.
OFF File Features
- Editable ASCII Structure: OFF files are plain text, easily viewable and editable in any standard text editor, making them perfect for manual modeling or debugging.
- Supports Polygonal Geometry: Store 3D shapes using triangle meshes, quadrilaterals, or general polygons. Each face is defined by a list of vertex indices, allowing flexible model design.
- Lightweight and Minimal: Unlike complex CAD formats, OFF excludes materials, textures, and metadata, focusing purely on geometric structure for fast, efficient modeling.
Convert OFF Files to Other 3D Formats
Our 3D conversion tools make working with OFF files fast and flexible. Autoconverter enables direct conversion of OFF mesh models to popular formats such as STL, OBJ, SKP (SketchUp), and PLY - preserving polygonal integrity throughout. For advanced workflows, Autoshaper can convert OFF files into NURBS-based formats like STEP, IGES, and BREP, ideal for CAD software and precision manufacturing.
