How to Convert ZWCAD to IGES?
Follow our straightforward 3-step process and export your ZWCAD drawings to IGES with professional-grade accuracy:
📥 Install Automesher Application
Download and install Automesher Application for AutoCAD, BricsCAD, GstarCAD, or ZWCAD - it adds the AmExportMesh command needed to export IGES files directly from ZWCAD drawings. Restart your CAD software after installation to load the plugin.
▶️ Run IGES Export Command
Type AmExportMesh in the command line and press Enter. Select the 3D entities you want to export from the ZWCAD model space - supported types include Polyface Mesh, Polygon Mesh, 3D Solid, and 3D Face - then press Enter again to confirm the selection.
💾 Save as IGES File
In the save dialog, select IGES (*.igs, *.iges) as the output format, choose your destination folder and filename, then click Save. Automesher converts the selected ZWCAD entities and writes them to your file.

IGES File Format - Initial Graphics Exchange Explained
The IGES (Initial Graphics Exchange Specification) file format is widely used across CAD (Computer-Aided Design), CAM (Computer-Aided Manufacturing), and CAE (Computer-Aided Engineering) industries for transferring 3D models and complex designs between different software platforms. Developed in the 1980s and standardized by ANSI and ISO, IGES remains a crucial, legacy-neutral format for 3D data exchange, ensuring long-term interoperability.
What is an IGES (.IGS) File?
IGES files store detailed 3D CAD data using a text-based format that can represent wireframes, surfaces, and solid models. It enables seamless sharing of geometric information without dependency on proprietary software, making it ideal for collaborative projects across engineering, manufacturing, and design fields.
Key Features of the IGES/IGS Format
- Text-Based Geometry Storage: All geometric and structural data is saved in human-readable ASCII text, allowing easy manual editing but often resulting in larger file sizes for complex designs.
- Color Information: IGES supports color at the assembly level, preserving important visual distinctions between different components and parts in a model.
- Transparency Limitations: Unlike newer 3D file formats, IGES does not support transparency (alpha channels), meaning that opacity settings in original designs are not retained after export.
IGES/IGS File Conversion and Processing
Autoconverter offers complete read and write support for IGES files using the Open Cascade technology stack, ensuring full compatibility with the latest IGES specifications. It processes IGES data as triangulated mesh geometry for maximum compatibility. For workflows requiring preservation of native NURBS surfaces and smooth 3D definitions, we recommend using Autoshaper, which maintains original surface accuracy throughout the conversion process.
