allegro PAD & footprint

[asadi.siyavash]

hi I used altium 3 year but now I need to design high frequency and impedance matching and DDR3 and etc so I changed my plane and I want to use allegro Cadence but I have many problem and I don't have good tutorial that start from orcad CIS shematic and end it in allegro PCB.
in altium designer we don't have PAD! I am confused!! I understood if I want to create new footprint I should attach it to pad that I created before.
but I found many footprint in the internet, with themselves PAD. is it need to attach my new PAD to them? how I can do? if it doesn't need why I should create PAD?
excuse me for my little knowledge in Cadence alllegro and also my bad English.
any help would be greatly appreciated.

Sincerely yours,
Siyavash.
