Offline to online alignment frustrations

Hi all,
So basically I am new to the whole cmm industry but i have spent a great deal of time trying to figure this out. We just acquired an offline license for programming our parts. We have never done this before and I can not figure out how to get my offline alignment to match the machines coordinates. I know you will probably say this has been answered but trust me I have read almost everything and was wondering if someone could give me a DETAILED description on how to do this.
Thanks,
Kevin

See i can go to the machine with the part.. take physical hits using the cad model online. Then go upstairs and program it offline. The problems lies in the fact we are not really fixturing these. They will be placed on magnets on our subplate, but without having a fixture for the part it is always a little off. So to compensate for this my supervisor suggested trying a secondary alignment on the part so the cmm will see EXACTLY where it is, because we are measuring rather small parts with slots that are tiny. Is this correct and I can paste the code if you would like. I really appreciate all the help
