🛠️ Convert AutoCAD to 3DM: DWG Drawing to Rhino 3D Model Converter

How to Convert AutoCAD to 3DM?

Say goodbye to complicated AutoCAD drawings to 3DM exports - our simple 3-step process gets it done fast and right:

  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 AutoCAD 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 AutoCAD 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 AutoCAD entities and writes them to your file.

ACAD AutoCAD DWG File Format - Convert DWG Drawings

AutoCAD, developed by Autodesk, is an industry-leading CAD software known for its precision, versatility, and native support for the DWG file format. DWG files are the standard format for storing 2D and 3D design data, widely used in architecture, engineering, construction, and manufacturing industries worldwide.

Key Features of AutoCAD and DWG Files

  • Comprehensive CAD Tools: Create professional 2D technical drawings and detailed 3D models using AutoCAD’s robust drafting and modeling capabilities.
  • DWG File Compatibility: Work directly with native .dwg files to ensure maximum data accuracy, cross-platform collaboration, and version control.
  • Custom Automation: Automate repetitive tasks and customize your workflow using AutoLISP, ObjectARX, and custom scripts for greater efficiency.
  • Dynamic Blocks & Parametric Design: Use smart blocks with adjustable parameters to simplify complex designs and speed up drawing creation.

Convert DWG Files to 3D and GIS Formats

Extend the power of AutoCAD with our Automesher Application and Automapki Application. These plugins allow seamless import and export of 3D model formats like STL, OBJ, SKP, FBX, and STEP, as well as geospatial formats including SHP, KML, and GeoJSON. Enhance your DWG projects by integrating 3D models and GIS data directly into your AutoCAD environment.

Convert DWG files and integrate real-world data into your CAD projects with ease - unlock new design possibilities and streamline your BIM and GIS workflows with our powerful AutoCAD 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.
