  • Iterative alignment

    Hi everyone,
    Is there an advantage using an iterative as opposed to say a 3-2-1 alignment when using customer models?
    Thanks in advance.

    Probably depends most on the actual model. If the datums are nice easy to define shapes, ie. planes, cylinders, lines etc. 3-2-1 should be fine. If datum A is a 12 foot diameter cylinder, and the part is about .5 degrees of that circumference and shaped like a helix, then an iterative alignment is better.

    Also, can be useful when using a Readpoint alignment. Iterate the rough alignment, then measure datums for a datum alignment.

      Any time you have specific DATUM TARGETS its a must.

        Iterative is alos better when you have complex surfaces as datums. or target points defined by engineering.
        Otherwise, I use a readpoint alignment.

          Depends on what your drawing specifies. For a part drawing with datum target points it is pretty much a must. Most of our parts (medical implants and instruments) are datum features are pretty much suited for a 3-2-1 alignment such as plane-line-line or plane/cylinder-circle-circle and such.

            I'd give you a whole nickel for that.
