What is an IGES file?
IGES (Initial Graphics Exchange Specification, latest version 5.3) is one of the oldest neutral CAD exchange formats, still common for surfaces and wireframe data between legacy CAD systems.
How to open an IGES file online
Drop your .iges or .igs file into the viewer below. Entities are parsed and rendered in your browser — rotate, zoom and inspect the model. Files are processed in local memory only.

FAQ
Can I view IGS files without installing CAD software?
Yes — this viewer parses IGES/IGS files in the browser. No installation, no account.
Is there a file size limit?
Local parsing runs within your browser's memory, so practical limits depend on your device rather than an upload cap.
Do you support IGES 5.3?
Yes, along with earlier commonly used versions of the specification.
