🏅 GstarCAD to 3DM: How to Convert DWG Drawing to Rhino 3D Model

How to Convert GstarCAD to 3DM?

Export GstarCAD drawings to 3DM accurately and efficiently - our proven 3-step process is designed for speed and precision:

  1. 📥 Install Automesher Application

    Download and install Automesher Application for AutoCAD, BricsCAD, GstarCAD, or ZWCAD - it adds the AmExportMesh command needed to export 3DM files directly from GstarCAD drawings. Restart your CAD software after installation to load the plugin.

  2. ▶️ Run 3DM 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 3DM File

    In the save dialog, select 3DM (*.3dm) 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.

GCAD GstarCAD - Convert DWG Drawings

GstarCAD, developed by Gstarsoft, is a powerful and cost-effective CAD software solution, known for its high compatibility with the DWG file format. DWG files are widely used to store 2D and 3D design data in architecture, engineering, construction, and manufacturing industries.

Key Features of GstarCAD and DWG Files

  • Robust CAD Tools: Design precise 2D drawings and detailed 3D models using GstarCAD's comprehensive drafting and modeling features.
  • Native DWG Support: Open, edit, and save .dwg files natively to maintain accuracy and ensure seamless collaboration across platforms.
  • Customization and Automation: Optimize workflows with support for AutoLISP, VBA, and GRX APIs to automate repetitive tasks and extend functionality.

Convert DWG Files to 3D and GIS Formats

Boost GstarCAD's capabilities with our Automesher Application and Automapki Application. These tools enable the import and export of popular 3D formats like STL, OBJ, SKP, FBX, and STEP, along with GIS formats such as SHP, KML, and GeoJSON. Integrate 3D models and spatial data directly into your GstarCAD projects with ease.

Convert DWG files and bring real-world context into your CAD environment - streamline your BIM and GIS workflows with powerful GstarCAD-compatible file conversion tools.

3DM 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.
