Nominals in DIMENSIONS keep changing!

Are you saying you probe a plane, line, and point (for example) then go to the alignment menu and align using those probed features?
I read somewhere... Level before rotating. I assumed that meant probe the plane, align that plane level, then probe the line... etc.
So, that's what I do. Am I doing it wrong?

IMO, yes, you are doing it wrong. When you open the alignment window, do the level, then rotate, then origins, then rotate about (if needed) then origin offsets, in that order, all in one go.

The only time you could possibly need to do an alignment that just does a level (at the beginning of a program) is if your level feature is WAY out of level to the machine, and if you know what you are doing, you don't even need to do it then since they added the ability to use a FEATURE as the reference plane for manual features in V3.7 (or was it V3.5?). AND, even if it IS way out of level to the machine and you CAN'T use a feature as the reference plane, you still don't need to do the 'single-step' alignment, just measure the plane and the line and the point and do the manual alignment, WHICH YOU DO FOLLOW with a DCC alignment, right? If so, the DCC alignment will 'correct' for the small amount of cosine error from the MANUAL level plane not being close to the machine plane. I've proved this many times, much to the embarassment of many "so called experts" who claimed otherwise.
