Learn how to import and export IGES files in Shapr3D, including CAD geometry, export settings, and compatibility considerations.
What is an IGES file?
IGES (Initial Graphics Exchange Specification) is a CAD file format used to exchange 3D geometry between different CAD applications.
IGES is commonly used for transferring surface geometry and exchanging models with CAD systems that support the format.
Import IGES files into Shapr3D
Shapr3D supports importing IGES (.iges and .igs) files containing CAD geometry. Imported geometry can be used and modified with Shapr3D's modeling tools.

Export IGES files from Shapr3D
Export your designs as IGES files to exchange CAD geometry with other compatible applications.
Save Solid As Faces
The Save Solid As Faces setting controls how solid bodies are represented in the exported IGES file.
- Enabled: Export solid bodies as individual faces.
- Disabled: Export solid bodies without splitting them into individual faces.
Enable this option when your destination application requires separate surfaces rather than complete solid bodies.
Additional export settings
You can also configure the following settings:
- File Name: Enter a name for the exported file.
- Include Hidden Items: Include hidden items in the export.
- Save Each 1st-Level Item Separately: Export first-level items as separate files, with file names based on their item labels.

Considerations when using IGES files
Surface and solid geometry
IGES is commonly used to exchange surface geometry. Depending on how the file is exported and interpreted by the destination application, geometry may be represented as separate surfaces rather than complete solid bodies.
Application compatibility
IGES is supported by many CAD applications, particularly for exchanging surface geometry. For workflows requiring solid-body interoperability, consider STEP or Parasolid when supported by the destination application.
