What is a .iges file?
model/iges
IGES (Initial Graphics Exchange Specification) is an older neutral CAD format for exchanging 2D and 3D geometry such as curves, surfaces, and wireframes as structured text records. It predates STEP and remains supported for legacy interoperability. It stores precise geometry rather than tessellated meshes.
How to use a .iges file
Use an example IGES file to test legacy CAD parsing, surface and wireframe import, and converters that migrate older geometry into STEP or modern tools.
