IGES (.iges, .igs)
New in 14[Experimental]
Background & Context

-
- MIME type: model/iges
- IGES is an acronym for Initial Graphics Exchange Specification.
- 3D geometry format.
- Commonly used for representing 3D models for computer-aided design.
- Binary format.
- Stores a 3D object, including a solid, as a surface formed by a collection of adjacent triangles.
Import & Export

- Import["file.igs"] imports an IGES file as a graphics object representing the surface.
- Import["file.igs",elem] imports the specified element from an IGES file.
- The import format can be specified with Import["file","IGES"] or Import["file",{"IGES",elem,…}].
- Export["file.igs",expr] exports a 3D graphics object to a IGES file. The expr can be any region that is ConstantRegionQ or a Graphics or Graphics3D object.
- The export format can be specified with Export["file",expr,"IGES"] or Export["file",expr,{"IGES",opt1->val1,…}].
- See the following reference pages for full general information:

Import Elements

- General Import elements:
-
"Elements" list of elements and options available in this file "Summary" summary of the file "Rules" list of rules for all available elements - Graphics representation elements:
-
"Graphics3D" IGES file represented as a Graphics3D object "GraphicsComplex" IGES file as a GraphicsComplex object "PolygonObjects" list of polygon primitives given in absolute coordinates - Import and Export use the "Graphics3D" element by default for IGES files.
