Granite is a geometric modeling kernel developed by Parametric Technology Corporation (PTC) which was mainly used in early versions of Pro/Engineer. Although superseded by ACIS since CREO releases, Granite is still used as the interoperability format in all Pro/Engineer releases. The Granite file extension is .g.
The Granite format is designed to facilitate interoperability between different CAD software applications. However, this format is only used by a limited number of CAD software, mainly PTC solutions. It allows to transpose the geometry without loss between software having the same geometry engine.
CAD Interop distributes several software for viewing and translating granite files. Find below the list of our solutions compatible with the Granite format:
