    I know this is a simple request if you know the answer, however I don't (as
    I'm new to orcad). I need to create extra pads with a larger than normal
    separation between it and any other pad or track or copper fill because it
    will have a high voltage on it.

    How do I create pads in the pad stack that will give me this large gap ?.

  2. You don't do anything in the padstack. The spacing you want is not an
    attribute of the padstack or footprint (because this footprint might be used
    in many places, only one of which has the high voltage). The requirement for
    the spacing comes from the net on which this pad exists.

    You need to set the required spacing as an attribute of the particular net.
    Go to the Nets spreadsheet, double-click on the net in question and select
    the Net Spacing button in the dialog.

    The help file says:

    " The Net Spacing By Layer dialog box appears when you choose the Spacing By
    Layer command from the Net submenu (available from the Tool menu). It is
    also accessible via the Edit Net dialog box by choosing the Net Spacing
    button. This dialog box allows you to override the track-to-track spacing
    parameter set in the Route Spacing spreadsheet. "
