    Updating design padstacks Reply
    Hi,

    I had a design with wrong padstack on a footprint, which has already been place on a board and routed.  I created a new and correct padstack named it as the old padstack after deleting the old padstack.  Even after deleting and replacing the footprint on the board, the old padstack remain on the board and I cannot get it to be updated to the new padstack.

    Can someone help as to how to update the wrong padstack to the new one?

    Software:  Allegro PCB Editor

    Your comments are highly appreciated.

    Sounds like you need to update the padstack all the way through the design sequence.  By this I mean:

    After redefining you new padstack, you need to update your footprint symbol to include it.

    • In symbol editor do a Tools > Padstack > Refresh if same name, or Tools > Padstack > Replace if different name.
    • Then its always best to purge any unused padstacks since the old one may still exist in the symbol definition.
    • Tools > Padstack > Modify Design Padstack will get you a pop-up menu with a Purge button, do all.

    After fixing and saving you revised footprint symbol, you can then replace it onto your board.

    • From PCB editor, Place > Update Symbols and select the revised one.

    Hope this helps.
