Convert DWG to 3DM - Pro-Grade Precise Drawing Conversion

DWG to 3DM Conversion

Exporting DWG drawings to 3DM? We have reduced this process to a three-step breeze:

1. Install Automesher Application

   Export 3DM files directly from DWG drawings using Automesher Application - simply install the plugin and restart your CAD software.

2. Execute 3DM Export

   Enter AmExportMesh in the command line. Then, select the 3D entities (e.g., Polyface Mesh, Polygon Mesh, 3D Solid, or 3D Face) from your DWG model space that you want to export.

3. Save as 3DM File

   Select 3DM (*.3dm) as file type, choose the destination folder and file name, then click Save to complete the export.

DWG 2D/3D CAD Drawing

A proprietary binary file format developed by Autodesk for storing 2D and 3D CAD (Computer-Aided Design) data, including vector graphics, metadata, and geometric models. As the native file format for AutoCAD, DWG is the industry-standard for engineering, architecture, and construction design due to its precision, versatility, and widespread compatibility.

Standout Features of DWG

• Compatibility: DWG drawings are compatible with other software packages, such as ZWCAD, Bricscad, and IntelliCAD, which also support the DWG format. This makes DWG files the industry-standard in CAD.
• High-Precision Vector-Based Design: DWG files store vector-based data, 2D drawings, and 3D models, along with metadata, making them highly versatile. Ideal for technical drawings and designs requiring extreme accuracy, such as engineering blueprints and architectural plans.
• Support for Blocks: DWG format supports for "blocks", which are reusable design elements like symbols or templates, which help improve efficiency, maintain consistency across designs, and reduce file size by reusing common components without duplicating DWG data.

DWG Drawing Converters

DWG drawings can be easily converted into various 3D and GIS file formats, such as OBJ, STL, DXF, KML, and KMZ, using our add-ons - Automesher Application and Automapki Application. This allows you to seamlessly share your AutoCAD DWG drawings across different platforms and applications. Convert DWG to SKP, KML, STL and more - try our converters with a free trial today!

3DM Rhinoceros 3D File

The native file format for Rhinoceros 3D (Rhino), a powerful and versatile NURBS-based 3D modeling software. As Rhino’s default format, 3DM is designed to store precise mathematical representations of curves, surfaces, and solids, making it ideal for high-accuracy modeling across industries.

Supported Geometry Types

Known for its precision and versatility, the 3DM format supports a comprehensive range of geometric data types, making it ideal for both organic freeform modeling and technical CAD applications, including:

• NURBS Surfaces: Enables mathematically precise, smooth, and editable surfaces essential for high-end industrial and automotive design.
• Polygonal Meshes: Stores tessellated geometry for 3D printing, rendering, and simulation.
• SubD (Subdivision Surfaces): Allows for flexible, organic modeling with editable subdivision geometry.
• Instance References: Lightweight object copies (not duplicates) that reference a single source, saving memory and ensuring synchronized updates.

3DM File Conversion

Our software solutions enable seamless conversion between 3DM and other major CAD formats (e.g., STEP, IGES, OBJ, DWG, STL). Autoconverter exports only polygonal meshes (STL, OBJ, etc.), suitable for 3D printing and real-time rendering, while Autoshaper preserves NURBS geometry, ensuring superior accuracy for CAD, CAM, and engineering workflows. Both converters can save 3DM files in legacy formats (Rhino 2.X - 7.X) or the latest Rhino 8.X version, ensuring smooth collaboration across different software environments.
