OffBIM turns building models into fabrication files
A web-based converter that claims to transform IFC building models into manufacturing-ready STEP AP242 files, retaining geometry, tolerances, and assembly relationships.
Field notes
The site describes a staged conversion from IFC semantic extraction through geometry conversion, AP242 post-processing, and NIST STEP Analyzer checking. Its documented outputs include STEP, STL, OBJ, JSON, CSV, and assembly reports; the page also says cylindrical holes become CYLINDRICAL_SURFACE entities and that dimensional tolerances travel in a companion JSON file. Access requirements for running a conversion are not visible in the supplied homepage extract.
