Old style start for program?

Hello all friends around world.

I am evaluating programs from our supplier now. One program with Plane Circle round slot datums starts with iterate alignment. I wonder whether this is old style start since It takes at least 5 mins on manual hits before running DCC.

  • ​Based on Neil posted on other thread. It should be very classic start with plane ( 3 points) line ( cast from circle and half circle) and a point. Anyone could explain to me why using iterate alignment?
    If the Tol is out, keep on manual hitting all those points ( I have another program for third party with similar start with tight tol)


    I agree. I don't think an iterative alignment is necessary for that part. It works, but it is more complicated than necessary.
    I'd probably just use a read point alignment that starts from the CIR1 hole, but I'd have to see the part geometry to say for sure.​
