Undimensioned Features

cmmjdl
I'm looking for an option that appears in Zeiss' Calypso hoping that there's a similar approach with DMIS.
When programming a complex part with a model, I like to program around the part in a logical manner measuring all features
I can reach. I then dimension what I've measured to the customer's drawing. There are occasions where a feature on the part
is not dimensioned on the drawing but I've measured it. Calypso won't run a non dimensioned feature thereby leaving that feature grey as an indicator is wasn't dimensioned. This prevents me from missing anything on the part whether it's been dimensioned on the drawing on not. DMIS on the other hand will measure everything, dimensioned or not.
Is there a way for me to tell that one of say 500 features is measured but not dimensioned with DMIS?

Thanks
  • You could just report the actuals with no tolerance.
  • At the end or the beginning put a comment to report stating that.

    And for those go to:

    Edit/Preferences/Parameters/Dimension

    Dimension output format? And unclick everything except


    Nominal


    Measured.




    Remember to reformat for the next job or dimension. You can format before and after each dimension as needed. For example if you want to show Min/Max. If you are doing a set you can show all the points in a set for a Profile if you use the ANALISIS features in the Profile Dimension Window
  • I read your question as "Is there a way to get PC-DMIS to inform me about features measured but not dimensioned in any way?". If so, the answer is "no, not out of the box".

    Technically, a Basic script could be written that collects all feature names, goes through all dimensions and [in some way] marks all the features that are dimensioned, and finally outputs a list of those features that never got a mark. Should be doable, but I have no real idea how complicated it would be before it's verified correct. And it would need updating each time PC-DMIS gets a new feature or dimension type.
  • I don't understand, if you don't put a dimension in for the feature it won't be on the report.


    Are you saying you want to show that a feature was measured (but with no dimension)?

    Do you just want the feature ID, or some information about the feature?
  • I apologize for the confusion. Simply stated, picture writing a program to the part, not the drawing. 'beeping' every single physical feature on that part. I get to the end and I begin dimensioning from the print. I want to know when I'm done, what features I 'beeped' that were not dimensioned by the drawing (maybe it was missed on the drawing, whatever). If anyone has any Calypso experience you'd understand what I'm trying to do. Of course I know how to modify dimension results.

    Sorry I misunderstood your question too.


    Why would you program that way? Not all features may need to be dimensioned. Some may be for manufacturing purposes only. If it is an assembly so of the features have already been dimensioned and are not required. Does the print callout

    "All General Surfaces to some Profile Feature Frame"
    "All Trim Edge to a Trim Profile Feature Frame"
    All Circular Features to some True Position Feature Frame"

    Or in some BLOCK does it say

    x.x = +/- 1.0
    xx.xx = +/- .05
    xxx.xxx = +/- .01 or something to that affect?
  • Would the reason be to trim unneeded features out, or to raise a question as to why they're not dimensioned?
  • My short answer is no I have not found a similar feature in dmis, and for all who have not used Calypo the program will not physicaly measure a feature if you have not reported a dimension it will just skip that feature end result can be broken probe as navigation is feature dependent in the vesion I used if using sub clearances

    So in pcdmis talk are you saying it will automatically UNMARK a feature because it has not been dimensioned on a report? So if I am using tooling balls on a fixture and using them only for alignment and they are not on the my print I still have to dimension them on my report?
