    Hello,

    One trick that I learned to accomplish this was to create a Placement Replicate of the circuitry.  Once it is a Place Replicate group you have the ability to Move / Mirror / Rotate it as one unit (group).  Once it is on your cursor during Move selecting Mirror from the Right Mouse Button (RMB) menu to mirror everything from top to bottom vertically, so if J1 was on the Left on the Top it will be on the Right on the Bottom.

    Here are the steps to create a Placement Replicate group:

    - Go into Placement Edit Application Mode (RMB in the background; Application > Placement Edit)
    - Select Symbols in the Find Filter and window the components/circuitry
    - RMB over one of the highlight symbols and select "Place replicate create"
    - It should highlight all the Clines/Vias/Shapes attached to the components.
    - You can now select/unselect any additional etch items that were not highlighted, then RMB Done.
            - NOTE: In order for a Cline/Via/Shape to be selected it must have a Net Name with a path back to a Pin.
    - Select the origin point for the Place Replicate group and save it to a local file.
    - You Done!   Now select Groups in the Find Filter and you can move the circuitry as one Group which gives you access to RMB Mirror

    I have frequently used Place Replicate to replicate circuitry on many designs, with the added flexibility to mirror the entire groups from one side of the board to the other. You should have access to the Placement Replicate functionality using an OrCAD PCB Designer Professional license up thru the Cadence Allegro products.

    Hope this helps,
    Mike Catrambone
