🔁 Convert GstarCAD to OFF: DWG Drawing to Object File Format Converter

How to Convert GstarCAD to OFF?

The fastest, most reliable way to export GstarCAD drawings to OFF is here - a clean, proven 3-step process built for results:

  1. 📥 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 GstarCAD drawings. Restart your CAD software after installation to load the plugin.

  2. ▶️ Run OFF Export Command

    Type AmExportMesh in the command line and press Enter. Select the 3D entities you want to export from the GstarCAD 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 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 GstarCAD entities and writes them to your file.

OFF 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.
