The STEP Python interface brings STEP-NC APIs into the Python environment for high-level operations on STEP assemblies and STEP-NC process descriptions. It also opens up the STEP data classes, previously only available in C++, for detailed work in areas not covered by the high-level operations.

The STEP Python interface is available on the Python Package Index (PyPI) for simple install with pip. Currently, the package allows anyone to read models but requires a license key from STEP Tools in order to write models. You can find STEP-NC sample data on ap238.org.
