Xact Measure problem

slesholdofthreep
Has anyone had problems with Xact Measure TP dims? I have various parts with MMC on the DF as well as the Datums. As may be expected the DF and the datums all have different size tolerances. When setting up the dimension I tolerance them correctly, but once created the datum tolerances default to the DF tolerance. I have assigned variables for tolerances with little success. In fact I can type in the correct tolerance right into the dimension in the edit window and.. pfft... it reverts back to the DF tol. I am attempting to use this "improved" method because the hexagoon's say that legacy TP dims don't account for MMC on the datums correctly. WTF!

I am running V4.2mr2, but I have seen this in 4.1 and 4.2mr1.

    I have found that when reporting TP with "Fit to Datums" ON, I cannot
    change some things (DF nominals, for one). Once I turn it OFF, changes
    can be made and applied.

    The selection "Datum Reference Frame" or "Current Alignment" also has
    some effect on the ability to make edits.

    We do not have parts that use BF on Datums, however. No help there - Disappointed

    I have not found any difference it its behavior regardless of FIT TO DATUMS ON or OFF nor have I found any difference between output to DRF or CURRENT ALIGNMENT.

    Jan, James, is my understanding correct that if there are VCs on the datums FIT TO DATUMS must be on?

    Another issue I had all but forgotten about. Sometimes the DF tolerance will change on its own to an impossible number such as +995412121231232111 -993452112111111111.
