Hi John,

I guess you want to access the product structure (or product hierarchy) from a STEP file generated using famous 3D cad packages, right? In that case, you have to use the STEP importer available from OCAF (STEPCAFControl_Reader). That's something I did in Python (see the classes STEPOCAF_Import and STEPOCAFExport at https://github.com/tpaviot/pythonocc/blob/master/src/addons/DataExchange/STEP.py), but I didn't port the example to C++. Let me know when you're done and if you want to share your results.

Thanks, Thomas,

I will give back any C++ examples I generate.

Hi Thomas,

Related to this, is there an *easy* way to attach names to solid shapes when exporting a STEP file? I've searched around and it doesn't seem like there's a straight example out there to do just that.

Best,
Jake

Hi John,

I have used the example code at http://opencascade.wikidot.com/entitynames for extracting entity names. It works well. But be sure to check the remark on the "Discuss" link on that page.

Bye,

Slightly OT, I found the answer to my own question. You have to set the static property "write.step.product.name" before each shape is transferred to the STEPControl_Writer, i.e.:

Interface_Static::SetCVal("write.step.product.name", "My part name!");
