Nominals in DIMENSIONS keep changing!

seppley
I have read most of the posts on this site, and they mainly seem to point to the nomials for the actual feature changing... and like most of you say " I have never had DMIS change a nominal ... ever! And if it is changing it on you , you have done somthing wrong!"

I am not talking about it changing a nominal for a feature! I am saying that when i create a dimension, without CAD, I have to tell it what nominal i want for the dimension, bedcause it always picks the wrong one! Then I print a report and all is fine... UNTIL I RUN THE PROGRAM AGAIN! Then, the next time i print the report, all the nominals are different and I have to update them again!

Also tolerances that i put in the angle dimension edit box won't transfer to the report at all.

Thoughts??

  • Somehow, this seem to happen to me everytime I import a CAD, clicking away on the model to create my features and then running the program...

    I made a program like this today and after measuring a plane I did a level and origin and then measured a circle and a slot (the THEO's taken from points clicked on the model).
    I ran it and noticed a small deviation in the theo's. I polished these up and moved my part slightly.
    Ran it again and noticed larger deviations in the theo's. Moved the part slightly more.
    Rinse, repeat - still getting theo's that deviated. Polished them again.

    Closed PC-DMIS, fired up the settings editor and looked up the UseTheosForCADToPartLevelAlignment. I changed the setting to TRUE (1), saved and closed the settings editor.
    Ran the program again and still got theo's that deviated. At this time, I almost blew a gasket, thinking that it didn't work.
    Anyway, I polished the theo's once more, saved and closed the program.
    Opened it up again and ran it. No deviating theo's!
    Moved the part slightly, ran it - no deviating theo's!
    I repeated this at least three more times, all resulted in the theo's staying the same.

    Heureka! Finally! (time for a happy dance!)

    So, all in all, it seems that the registry setting did the trick! Too early to tell if the setting affects something else though... (knock on wood)
