C# NX二次开发-获取图档全部实体

 使用 UF_OBJ_cycle_objs_in_part 函数遍历图档全部实体。

      var theUf = UFSession.GetUFSession();
      var list = new List<Tag>();
      var solid = Tag.Null;
      var d_part = theUf.Part.AskDisplayPart();

      while (true) {
        theUf.Obj.CycleObjsInPart(d_part, UFConstants.UF_solid_type, ref solid);
        if (solid == Tag.Null) break;
        theUf.Obj.AskTypeAndSubtype(solid, out var type, out var subtype);
        if (type == UFConstants.UF_solid_type && subtype == UFConstants.UF_solid_body_subtype) {
          list.Add(solid);
        }
      }
