I got this library (see Image), online, that contains objects for household electrical components, and I am trying to make each object as a symbol into my IEC library but I can not do it. I tried this link here but nothing happened. And I tried using symbol builder but can't add into IEC library, because it browse file into JIC or Pneumatic or Hydraulic. So anyone can give me a method to save every object in the picture as a symbol and use it always in an IEC library.
