if I'don't whirlwind. OCC doesn't put some ID on their entities "TopoDS & Geom" like for example STEP, ACIS...etc (#100# advanced_face...)
my Question is how to set an ID(name or integer refere to Entitees Topology & Geometry) in the first time, and to send this ID to OCC in the second time, and finally get him, to retrive the shape and Geometry OCC.
ANY IDEA MAY BE VERY HAPPY. please Help
