  • Xact Measure True Position with different diameters

    First off I'm running DMIS 2019 R1. I have a composite true position of 5 circles. The top is [email protected] to A/B/C and the bottom is [email protected] to A. DMIS will not let me select all 5 circles in Xact Measure because they are 2 different sizes.

    Proprietary, export controlled, and ITAR print so the above "illustration" will have to do.

    My workaround is I true positioned all 5 circles [email protected] to the current alignment (part is aligned to A/B/C) in legacy, realigned the part leveling and translating Z axis to datum A and translated X and Y to the bigger center circle, then true position the 4 smaller circles [email protected] to the new alignment also in legacy.

    The question(s) here is, is there a way to force Xact Measure to use all 5 circles with different diameters in the same dimension and if not, is my workaround the best way to do it?
    Remembering my beautiful wife Taz who's life was taken from me on 6-13-2020. I love you and I miss you.

    i mean as long as you're in the correct alignment your calculations should be the same. The only thing you'd lose out on are any modifiers to datums. Otherwise, sounds good.

      Edit: Shrocknroll is totally right. I looked up simultaneous evaluation in the help file and it was designed for situations like this.

        Do you have a code example of how to create the generic feature and apply the deviation from the actual circle?

        I like this idea. I use generic features, not a lot, but I do use them. I don't know why I didn't think about it before.

      Create both XactMeasure positions separately then use simultaneous evaluation to tie them together.
