Quick question pertaining to Runout,
As a rule I was told, If you pick the datum last you will never go wrong??
I this true?
I construted a circle (cone with plane) and call it out to Datum -B-,
the results was no deviation.
If I reverse the picks (datum 1st) the results does have deviation which
I believe to be correct.
Thanks in advance for the input.
