I created a shape symbol for a surface mount (SM) pad and pulled it into a new package symbol. I changed the original shape of the symbol and pulled the changed shape into the Padstack Editor, with the intention to overwrite the old padstack. Now I want to change the old pin in the package symbol with the new pin, however all it pulls in is the old pin. How can I most effectively modify the pin? 



To update a shape within a padstack, select Tools > Update Symbols. This opens a form with the shape symbol listed similar to what is shown in the screen image that follows.



Select the check box next to the shape symbol name then click the Refresh button.
