I am new to OpenCascade and BRep, STEP and other file formats. I am trying to mesh some
BRep models using NetGen, Gmsh and other public domain software.
I am stuck with one problem. I am interested in comparing results with various software
( and sometimes for debugging) and it seems that different readers assigns different
integer IDs for different geometric edges/faces in the model. Therefore, I am unable to
get one-to-one matching from different software.
My naive question is: Who assigns the Integer IDs to the model entities ? I guess that
it must be included in the model itself, so different readers must give back the same
entities, but it is not happening. How can I have get the same geometric entities ?
