How to do a base alignment without a solid model with the romer arm?? - new user

Good morning
I am a brand new user with the romer arm. Could any one direct me on where to obtain the information I need to get started with a base alignment? Please and thank you.

  • Since the alignments differ from part to part, there really is no "general" approach.
    Depending on how you "do it" with a CAD model (select/measure the features from the CAD and then directly to best-fit) you WILL have to do some manual work.

    If you could post a snippet of the drawing or something I am sure you can get much better answers.

    The generic method goes something like this (plane and three holes):

    Measure the plane.
    Correct the theoreticals.
    Primary alignment on the plane and maybe an origin.
    Measure the three holes.
    Correct the theoreticals for each hole (both coords and vector) according to the drawing.
    2D-best fit alignment using the plane axis (you should have aligned the plane in this axis) as restriction plane and select the three holes.
    Hit calculate then create.
