I haven't had to dimension total runout yet programming. I am fairly new with programming and was looking for some advice on the best way to dimension these Total Runout callouts.
If you want to use legacy, select the runout feature first, and the datum second.
I prefer to use a auto cylinder spiral scan for the feature with a reasonably tight pitch to mimic a hard gage if possible.
Concentric circle scan for the Datum.

You need to measure datum A as a plane, spreading the hits over as much of the surface as possible and then level to it. You then need to measure datum B as a cylinder, create a pierce point between A and B and origin to it. You can then measure your other cylinders and planes and report total runout back to the active alignment using legacy.
It will depend on how square the cylinder is to the plane. When you origin to the cylinder it will use the axis average. By creating a pierce point to use as the origin, it makes the alignment more repeatable and more closely simulates the way the datum reference frame would work.
Yes but you can safely add a rotation to fully lock down the alignment without it making any difference to the runout results. It's actually advisable to create fully constrained alignments - there are many other post on that subject.
