Customers can use an arbitrary .exp file (for STEP Application Protocols, CIS/2, IFC or even others) which defines format with EXPRESS schema. ODA STEP SDK can work with geometry of AP203, AP214, AP242ed3, DOMAIN\_MODEL and CIS/2 formats. The appropriate .exp files are provided as part of release archives.
