# step-conformance parts STEP files of parts whose exact shape is known, generated from formulas by [step-conformance](https://github.com/dan335/step-conformance) (`corpus/generated`, commit 96f30bb). The corpus is dedicated to the public domain under CC0 1.0. `step_in::tests::step_conformance_parts_read_back_their_exact_shape` in `crates/kernel` reads each one and checks its volume against the generator's profile, its box and its face count.
