About this 3D viewer
Open IGES or IGS CAD files online for engineering-model review. IGES is a long-established neutral CAD exchange format, and compatible surfaces or solids are tessellated locally so the geometry can be inspected without installing a CAD application.
IGES and IGS files from CAD exchange workflows
Inspect compatible IGES or IGS geometry in a current Windows, macOS, or Linux browser after export from CAD tools such as SolidWorks, CATIA, Creo, Fusion 360, or FreeCAD. The browser tessellates geometry for display and does not expose original CAD history or complete topology.
How to use this IGES viewer
- Sign in and unlock IGES Viewer once.
- Upload an .iges or .igs CAD exchange file.
- Review compatible tessellated geometry or continue with IGES to GLB for web sharing.

IGES viewer FAQ
How do I open an IGES or IGS file?
Unlock IGES Viewer once and choose the .iges or .igs file for compatible local browser processing.
What is the difference between IGES and IGS?
They are common filename extensions for the same IGES CAD exchange standard.
Can I convert IGES to GLB?
Yes. The related IGES to GLB Converter exports compatible tessellated geometry as a web-ready GLB.
What is an IGES file?
IGES is a neutral CAD exchange format used to share engineering surfaces and solids between applications.
Is IGS the same as IGES?
IGS and IGES are commonly used filename extensions for the same exchange standard.
Can I open IGES files online for free?
The browser preview requires the one-time $1.90 format unlock; compatible geometry is processed locally.
Can I view an IGES or IGS export from SolidWorks, CATIA, or FreeCAD?
Yes, for compatible exchange geometry. Use the original CAD tool for precise surfaces, assemblies, feature history, PMI, and manufacturing validation.
What file extension does IGES use?
This tool accepts the compatible IGES extension shown in the upload area. Use the dedicated format viewer when a file has a related extension or an application-specific variant.
Can I use this IGES viewer on a phone?
The page can be opened on mobile browsers, but a desktop browser is usually more practical for large files and detailed orbit, zoom, and inspection work.
Do I need to create an account to preview a IGES file?
Yes. Sign in first, then unlock this IGES tool once for $1.90. VIP members can also access the viewer.
