Our free and fast tool will convert most IGS (Initial Graphics Exchange Specification) CAD files to a standard USD (Universal Scene Description) 3D model file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing. Our conversion tool can also batch convert multiple IGS files; up to 200 files at a time can be converted.
To convert your IGS file, click the Upload button above and select the file to convert. Once selected, the file will be converted to a USD file and will be ready for download shortly afterwards. For more information about the IGS to USD conversion process, see the conversion information section below.

IGS is an open file format used within CAD applications as a means of saving data in a format that can be opened and edited in other CAD applications. Its roots can be traced back to the mid-1970s, when it was used by the United States Air Force.
The format itself is a human-readable text-based format and contains data that can represent many different CAD elements, such as points, lines, arcs, and much more. IGS files can be opened with many modern CAD applications, such as FreeCAD.

The USD format is a relatively new 3D file format developed by Pixar in 2016. The format is open source and has the support of major players in the space, such as Apple, Adobe, and more.
USD files encapsulate a full 3D scene along with any associated 3D models, animations, and visual effects into a single compact binary file. USD files can be opened with most popular 3D editing software, such as Blender.
Yes! Our IGS tool supports full batch conversions. You can upload up to 200 IGS files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the USD files individually or download them all in a single ZIP file.
First click the "Upload..." button, and select your IGS file to upload. You can also drag and drop your file onto the tool. Once your file is selected, you can set any configuration options. When the IGS to USD conversion has completed, you can download your USD file straight away.
We aim to process all IGS to USD conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.
We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.
Yes, of course! We do not store the IGS file you submit to us. The resulting USD file, once created, is stored for 4 hours after upload; after this time it is deleted, and the short-term download link will stop working. You can create a long-term download Url with most tools that will ensure the file is retained for 24 hours, allowing you to download the file when convenient. Our tools also come with a Delete button, allowing you to delete the file immediately.
