Can I Open IGS File in AutoCAD?

If you’re working with AutoCAD, you may come across the need to open a file with an .igs extension. The .igs file format, also known as IGES (Initial Graphics Exchange Specification), is a widely used format for exchanging 2D and 3D design data between different CAD systems.

What is an IGS File?

An IGS file is a neutral file format that allows interoperability between various CAD systems. It contains information about the geometry, structure, and attributes of a design. This file format is widely supported by CAD software, including AutoCAD.

How to Open an IGS File in AutoCAD

To open an IGS file in AutoCAD, follow these steps:

  1. Launch AutoCAD on your computer.
  2. Go to the “Insert” tab on the ribbon menu.
  3. Click on the “Import” button in the “Import” panel.
  4. A new window will appear. Browse and select the desired IGS file from your computer.
  5. Click on the “Open” button to import the IGS file into your current AutoCAD drawing.

Tips for Working with Imported IGS Files

When working with imported IGS files in AutoCAD, keep the following tips in mind:

  • Scaling: Check the scale of the imported geometry and adjust it if necessary using appropriate scaling commands in AutoCAD.
  • Editability: Depending on the complexity of the original design and how it was exported to the IGS format, some elements may not be easily editable in AutoCAD. Make sure to review and understand the limitations before making significant modifications.
  • Layering: Organize the imported geometry into appropriate layers for better management and visibility control.
  • Compatibility: While AutoCAD supports IGS files, it’s always a good practice to ensure that you have the latest version of AutoCAD installed for optimal compatibility with various file formats.


In conclusion, AutoCAD provides support for opening and working with IGS files, which are commonly used for exchanging CAD data between different systems. By following a few simple steps, you can import an IGS file into AutoCAD and work with its geometry.

Remember to consider scaling, editability, layering, and compatibility aspects when working with imported IGS files. With proper understanding and utilization of these features, you can efficiently incorporate IGS files into your AutoCAD workflow.
