Measuring the size of a 3 Sided Polygon

Hello Everyone,

Just a cmm noob with another question. My company needs me to verify thesize of a polygon (3 sides). We do not have a go/no go pin in yet and they are asking for answers. PCDMIS is showing the Polygon to be larger than nominal and they do not believe my results. (Measured as Auto Polygon) Is there a secondary study I can do to prove the size of a polygon without using Auto Feature and in your experience is Auto feature on a polygon reliable when it comes to measuring Diameters. I would assume I need to do some sort of study and measure from the center of the rads to the Middle of the opposing lines and do some sort of Intersecting points. Using PCdmis 2021.1

Thanks in advance to anyone who answers.

you can do a section scan or a closed linear scan. However, be aware of where the START and STOP are located make sure they are not on the "peak" of the radii. This would be for the PROFILE OF A LINE. do individual scan over the radii to find the Extreme point. I believe I asked about adding an auto feature for this. Don Ruggieri . It can be tricky to align to when it is on the end of a shaft with no flats. I see these all the time because they are great for keyless power transmission where sanitation is a concern.
