I am working in a new .dra file in the Symbol Editor and when I save the symbol I receive the error:
"ERROR(SPMHCS-1): Symbol is missing a refdes"  

How do I add the RefDes? 



You can add reference designators in PCB Editor by completing the following steps.

  1. Select the Add > Text menu.
  2. Set the Class and Subclass to “Ref Des” and “Silkscreen Top” in the Options form located on the right of the screen.
  3. Select a starting point and type a Ref Des “placeholder” such as J*.  
  4. When you later run Import Netlist, the placeholder is substituted with J1 or J2, etc.
  5. When you save the symbol the error will be resolved.
