I hired a new guy and he insists upon doing one DCC alignment and never doing another alignment, he lets the feature control frame control the alignment for him. I don't think that is a good practice, does anyone have an opinion on this?
If
all dimensions are FCF (no Legacy), and the part is
reasonably correct, you only
need one DCC alignment to drive around and collect the hits. You might need/want more if you use Legacy dimensions (to match the DRF), if the part is bad (local alignments to be able to collect the points - relative measure might be an alternative), if the tolerances are really tight (to minimize cosine error), if you like to see coordinates matching a certain alignment, and so on.
