Title says it all; I'm looking for libraries (really any language) to work with the most common 3D CAD data formats (STEP and IGES files). So far after looking with Google, Google Code, Github, and Freecode (freshmeat), it looks like the only reasonable choice is OpenCASCADE. Just about every other program or library that has this capability uses it in the backend.
Just wondering if anyone else knows of any libraries like this off-hand. Thanks!
