In the function GetSensitiveForFace in the file StdSelect_BRepSelectionTool.cxx, if the following codes are commented out, for a body of revolution generated by rotating one polygon, we can complete the selection operation correctly.

    else if (Handle(Geom_CylindricalSurface) aGeomCyl = Handle(Geom_CylindricalSurface)::DownCast (aSurf))
    {
      const gp_Cylinder aCyl = BRepAdaptor_Surface (theFace).Cylinder();
      gp_Ax3 aPos = aCyl.Position();
      gp_Dir aDirection = aPos.Direction();

      if (isCylinderOrCone (theFace, aPos.Location(), aDirection))
      {
        const Standard_Real aRad = aCyl.Radius();
        const Standard_Real aHeight = getCylinderHeight (aTriangulation, aLoc);

        gp_Trsf aTrsf;
        aPos.SetDirection (aDirection);
        aTrsf.SetTransformation (aPos, gp::XOY());

        Handle(Select3D_SensitiveCylinder) aSensSCyl = new Select3D_SensitiveCylinder (theOwner, aRad, aRad, aHeight, aTrsf, true);
        theSensitiveList.Append (aSensSCyl);
        return Standard_True;
      }
