Could you build this?
No Diffing complex 3D CAD assemblies from STEP files requires specialized computational geometry algorithms, boundary representation (B-Rep) parsing, and industrial CAD kernels.
What it would actually take: Requires an industrial computational geometry engine such as Open CASCADE (OCCT) wrapped in C++ or Python to parse STEP (ISO 10303) B-Rep topologies. The diffing algorithm must perform topological graph matching, spatial alignment (ICP / transformation solving), and boolean geometric difference operations to isolate altered faces, displaced solids, and feature deletions. Deep domain expertise in mechanical CAD data formats, geometric modeling kernels, and 3D rendering pipelines is necessary.
