Angularity tolerance on a surfance

PC-BIAS
How do I set this value (see Picture) in PC-dmis 2013 SP5? I've tried to create both planes and geometrical sets but the dimension feature Control frame window won't show me the "2,6/100x100" option Confused Can anyone help me?Slight smile


  • I do not think that PC-DMIS currently supports this. Whatever this surface is, take a grid of points at less than 50mm spacing, then you can create groups of features that are slightly less than 100 by 100 square that you can dimension. (ie, at 49mm spacing, you could have 9 points at 98 x 98 per square.)
  • What standard are you working to?
    That looks like a flatness callout to the 2009 ANSI not angularity

    Exact-measure flatness will support the 100 X 100 Flatness per Unit

    +1 !
    Insert it in a loop with a shift of 49 mm and dimension the angularity in the loop.

    Rich, I think you're right on this. It didn't click when I originally replied. I took a second look through the Form and Orientation sections, and couldn't find "per area" in reference to Angularity at all. Conceptually, it could work. Angularity also controls flatness, but flatness should, if critical, be controlled as a refinement of the angularity. So, this callout, is not likely to be a valid (to the text) callout.

    I'm going to make a song called and "An angle is an angle no matter how far it goes" one day.
  • Are you also going to make a song called "Angularity is not an angle measurement"? Slight smile Angularity is a tolerance zone defined by two parallel planes set at a basic angle. (Or cylindrical, but that doesn't apply here.) An angle has a tolerance zone shaped like a slice of pie.

    Mmmm, pie.
