Starting for IGS is a bad idea: all the entities are already duplicated in the file - load the IGS file alone and display e.g. the curve or surface tags to convince yourself. If you cannot create the geometry directly within Gmsh I would advise importing your geometry as a STEP file (or BREP if you build it with an OpenCASCADE-based CAD modeler).
