Feature Set to Surface Profile

boydha
Hi, I am new to the forum so please be considerate.

When you are creating a feature set and say you put in a circle, a line, and a plane, to create (scn1) when you output (scn1) as a profile Form+Location and MaxMin does this give you the profile of each individual point in those features or a profile of the centroids of those features?

If the centroids, Is there an easier way other than probing all the points over again or probing all the points and then creating your features to get what I am looking for?

Thank you for your help!

  • PROFILE compares each hit against its nominal value (or re-pierces the CAD if FINDNOMS is ON), not to the geometric form of the original feature. We don't know what DATUM A is, or how it is measured - it needs to be an autofeature (clicked on CAD or numerically entered) to have real nominals on every hit. If it is a "measured feature", the nominal value for each hit is equal to the measured value when the program was learned, and no form deviation will be detected in the original run. If you run the program again (preferrably on another part) you would probably get higher numbers, but still wrong.

    That makes sense how that would be the error if I was manually probing the points and trying to output a profile (I understand how that doesnt work.) However this was to a cad model auto feature plane. I've looked through some of my older progams and concluded that the results of .0001 flatness were probable considering "Datum A" is a machined flat plane. With a span of about 2.0"x3.0" the scan was leveled and origined at the plane.

    I was just wondering out of the two methods I have shown above why I am getting a different deviation /and what one would be correct.

    *see the edited highlighted text above* My reasoning is that these outputs are the same 8 points therefore their output deviation should be the same. unless there is an error in how I am recalling the points in one of them.
