Hello Vico, can you provide some ground for your request 'should'? Can you refer to some STEP Recommended Practice, or your own experience? |

Hello ABV, I had tried to export the model of WIRE with several edges and then load it back from the step file to OCCT: The result is a compound of edges after loading and i can't find the WIRE in the result model. I had read the user guide occt_step.pdf about the STEP and OCCT shape mapping: the STEP composite_curve will map to TopoDS_Wire while TopoDS_Wire will export to STEP geometric_curve_set. From my point of view, geometric_curve_set is more likely the compound and composite_curve is more likely WIRE in OCCT concept. Regards, Vico |

Ok, that sounds reasonable (and I recall we already discussed similar request some time ago). Note that in general case wire in OCCT may be non-manifold, thus we need to check that the wire is connected and manifold before deciding to map it to composite curve. |
