Composite true positions in Legacy

I'm being required to use Legacy GDT reporting for a program.
I haven't used legacy before and need help on how to measure/report these composite true positions using it.

Datum A is a surface
Datum B is a bore
Datum C is a bore
I have my alignment set up to ABC.

In TP#1 how do I ignore C to get the AB alignment?
and how do I get just B for the composite?

In TP#2 How do I get the composite with no datums?

Can Legacy do MMC bonus or MMB datum shifts?


TP #1:

{"data-align":"none","data-size":"medium","data-tempid":"temp_22355_1648740249085_596"}
TP #2:

  {"data-align":"none","data-size":"medium","data-tempid":"temp_22356_1648740215078_727"}    ​​

    What typed of measurement difference would be alarming to you if you did a composite profile of a surface with in the newer geometric dropdown deal vs the legacy best fit deal? I tried your above method and the bottom A|B section max measurement value was off from the geometric by .010". The analysis graphic output was quite similar and showed all points relatively similar in their shift pattern. If you are interested I can post it on here, but I only have a couple more days at this school, so I've been tidying up some of the tutorials I've made and fixing some old programs before I new what I was doing.
