removing pins from symbols

Question

hello: 
 
 is there a way to remove pins from a symbol that is already registered in the edit part list? 
 
 i know that pins on a symbol can be moved after unlocking the symbol. 
 
 but i would simply like to remove pins from the symbol without changing the symbol file (.dra). 
 
 regards

Hi Masa, 
 So the symbol needs to have pins because the pins contain the electrical information such as the netlist. The pins cant be removed without physically removing from the DRA in the symbol editor. If your in the PCB editor and there are pins with a padstack you want to remove, they can be replaced by what is called a null padstack. Basically this would be a padstack that only contains mask layers. That means the physical etch would no longer exist in the padstack such as top, bottom internal layers etc. To try that out go to user preferences and search for null. "Padstack_Allow_Null" , Enable that option. You would also need to create a badstack without any etch layers to use as the replacement. When you have that padstack created in the pcb editor simply replace the padstacks you want with the new null padstack. The pin will still remain in the symbol but the actual etch will be gone. 
 Best regards.
