RE: Primary Secondary and Tertiary Datum Planes
Perhaps the most important one that sprins to mind is that they should be selected based on function..
See if any of the stuff here helps: http://www.tec-ease.com/gdt-tips.htm

Again it seems you need to do some reading and hopefully get some training.
KENAT,
Have you reminded yourself of FAQ731-376: Eng-Tips.com Forum Policies recently, or taken a look at posting policies: http://eng-tips.com/market.cfm?

You can place the part on C (primary) locate it to A (secondary) and position it to B (tertiary).

RE: Primary Secondary and Tertiary Datum Planes
See para. 4.3, at least that's where it was in the '82 std. From that para., "The desired order of precedence is indicated by entering the appropriate datum reference letters, from left to right, in the feature control frame".
I.e. the OOP can vary from feature to feature.
