    Do the primary , secondary and tertiary datums need to be perpendicular to each other always ( when specified).

    if the datum is speced with perpendicular tolerance then they gotta be. If its on the print..part must conform to it. The exception being a POINT in space..how do you confirm that it is perpendicular??
