"Cannot find Nominals"

nooners4
Hi,

I am having an issue when running a programme on PCDMIS 2014 SP4. A "cannot find nominals" text box is popping up when running certain programmes.

What I would really appreciate is, what exactly is causing this to pop up and are there any consequences for ignoring the message.

For Example if I click yes and update previous scans or if I say ignore and don't update scans, will this have an effect on the results?

I am not the one who writes the programmes (Guys in the US do this O am from Ireland!) and our programmers don't seem to know how to resolve the issue nor do they know what are the consequences for selecting yes or no on the text box.

A fix for this and some insight into how and why it comes up would be seriously appreciated!
Thanks,

Cian

    Cian,
    Tell the programmers to edit their scans and increase their FINDNOMS Tolerance values.
    PC-DMIS performs the scan, recording raw data that's "ball center", then looks for nominals on the specified CAD surfaces - and finally offsets the actuals by the calibrated stylus radius and delivers the results.
    What can happen is if the FINDNOMS Tolerance value is too small, like equal or less than the stylus radius - then it cannot look far enough to find the CAD at all!

    Good luck and let us know how it works out.

    And tell your boss to send you to training so you can become proficient at programming and not have to rely on those dodgy Americans.
