Polygon question - hex longer than width; datum feature; True Position

wish2bflying
First post; be gentle. …

I've been given this shiny turd. The hex length is greater than the width. I've constructed a width feature across the two hex shapes to use as my Datum B "feature of size", but I'm a little stumped on how to report the TP of the polygon when it doesn't show the size properly. Have I missed some feature where I can tell PC-DMIS that the hexagon shape is longer than it is wide? You can see the points I've taken that show the true shape of the hex shape. I thought there might be a "constructed polygon" option, but I haven't found it yet.

I've searched the forum but didn't find anything like this. Most of the discussion of polygons is of regular shaped ones.

  • It doesn't look like you're being asked to dimension any hexagons. It looks like you have two slots that are equilateral triangles on each end.

    Create intersection points on the two lines at each end, and a midpoint between those points. Dimension the distance from intersection point to intersection point. Construct a generic circle centered on the midpoint with diameter equal to the distance.

    B can be made with a variety of different techniques.
