I am using FreeCAD to analyze a STEP file. I know that FreeCAD uses OpenCascade to open STEP files. Now I would like to know for a specific vertex what the line numbers in the step file are, so that I can pass this information to another program. Is there a way to extract the line number information after a Vertex has been loaded in the OpenCascade environment?
I have read through this page: https://www.opencascade.com/doc/occt-7.0.0/overview/html/occt_user_guides__step.html but I could not find the needed info.
I would need an attribute that looks like this:
object.Shape.Vertexes[0].steplinenumber
OpenCASCADE does not offer that. Implementing a feature like this might be difficult for shapes whose definition spans more than one line. Also the benefit of such a feature would probably be limited to very rare use cases.
