I'm relatively new to both OCCT and the STEP file format. We're investigating whether or not OCCT's STEP support is sufficient for our needs. I've managed to write code in C++ to read & write simple shape geometry to/from a STEP file. However, I can't find any way to deal with all the other metadata & user-defined properties that can be attached to an AP203 or AP214 entity. Can OCCT handle those properties? If so, how?
