  • iterative & best fit alignment

    Hi folks,

    Im often use 3-2-1 alignment for all of our mesurement routine.
    My question is can i use iterative alignment & best fit alignment without using a cad?how does it work?TIA

    The only reason for CAD is to pull the nominal X Y Z I J K values. As long as you know these, you can put them in the theoretical values of the features and best fit or iterative alignments will work just fine.

      thanks jeff
      But i don't have any idea how it works.
      We have a part with a complex surface (casting) and the tolerance is 0.005"
      I will post the blueprint later.
