    It looks like 3 exactly the same shapes.

    With this assumption, the way I would approach this issue:

    1 Create a shape in Solidworks (sorry if you don't have) or Auto CAD.

    2. Export  shape as a DXF

    3. Import into Allegro as a shape symbol

    4. Create a pad using the shape from shape symbol save.

    5. Create a new footprint from the pad.

    This is where you can rotate and add a via.

    Good luck.
