Convert IGES to AD_PRT

Understanding IGES and AD_PRT file formats

IGES (Initial Graphics Exchange Specification) is a widely used neutral file format for exchanging 2D and 3D CAD data between different CAD systems. It stores geometry, annotations, and other design information in a text-based format, making it ideal for interoperability.

AD_PRT is the proprietary part file format used by Alibre Design, a 3D CAD software. The AD_PRT format contains all the parametric modeling data, features, and design history specific to Alibre Design, enabling advanced editing and assembly operations within the software.

How to convert IGES to AD_PRT

Direct conversion from IGES to AD_PRT is not possible using generic file converters, as AD_PRT is a proprietary format. The recommended approach is to import the IGES file into Alibre Design and then save or export it as an AD_PRT file.

Step-by-step conversion process using Alibre Design

1. Open Alibre Design on your computer.
2. Go to File → Import and select your IGES (.igs or .iges) file.
3. Follow the import wizard to adjust import settings if needed (such as units or healing options).
4. Once the IGES file is imported and the geometry appears in the workspace, go to File → Save As.
5. Choose AD_PRT as the file type and save your part.

Recommended software for IGES to AD_PRT conversion

• Alibre Design – The native and most reliable solution for converting IGES files to AD_PRT format.
• Other CAD software may import IGES, but only Alibre Design can save as AD_PRT.

Tips and considerations

• Imported IGES files may lose parametric features; only geometry is typically transferred.
• Check and repair geometry after import to ensure model integrity.
• For best results, use the latest version of Alibre Design.
