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
Profile points could have also discovered that quickly. But what you did works good as well. I like using individual points so I can actually see what the surface is doing. is it straight? Is it tapering? Ect...
The OP,s method will not give the correct size if all three angles are not identical, the greater the difference between the angles the greater the error it is to the correct way to get the tangent circle.
