Open ShareCAD ViewerWhat Is an IGES File?
IGES (Initial Graphics Exchange Specification) is one of the oldest neutral formats for CAD data exchange, originally developed in 1980 by the US Air Force and National Bureau of Standards. Despite its age, IGES remains in active use, it is deeply embedded in aerospace, automotive, and defence supply chains where legacy systems and long-running programs make format migration difficult.
IGES stores NURBS surfaces, solid geometry, wireframe, and annotation in a text-based format. Opening an IGES file typically requires a full CAD application like CATIA, NX, CREO, or a dedicated IGES translator. An IGES viewer online through ShareCAD removes that dependency, the geometry renders directly in the browser.
ShareCAD lets you open IGS files without CAD software and share them via secure links with reviewers, procurement teams, or external partners who do not have access to industrial CAD tools.
IGES Viewer Use Cases
Aerospace and defence supply chains
Suppliers in aerospace and defence frequently receive IGES files from OEMs. A browser viewer lets them confirm geometry without expensive CAD licenses.
Legacy data access
Many engineering organisations hold archives of IGES files from past projects. ShareCAD makes those files viewable in a modern browser without maintaining legacy software.
Procurement and supplier quoting
Send IGES models to suppliers for quoting and manufacturing review via a link. Suppliers open the geometry without needing the originating CAD system.
Client approvals on surface geometry
Surface models for tooling, moulds, and complex geometry are often exchanged as IGES. A browser viewer gives clients a direct view without a CAD license.
