I am creating a Python library for reading CAD files in IGES format.   I have barely started on the project–so far, it should be able to parse arbitrary IGES files without crashing, and it can extract useful information for line segments and rational B-spline curves.   That’s all I need to get my work done right now, so I don’t feel justified in spending too much more “company time” on this.  I am hoping that other people will help me by adding Python classes to represent the types of entities that they need.

• Github repository
• Download the IGES standard (free) (link to PDF is towards the bottom of the page)
• Example files from the IGES standard (to be used for unit testing, eventually)
• More IGES test files
