Just trying to figure this out - when I dimension a circular feature I'll get one size but when adding a GD&T dimension for that same exact feature I get a different size altogether (example below). What's the reason for this?
Good question. Why does Hexagon make things worse? I recall years ago the QC team (at one place I used worked at) was scratching their heads why when using Xact the results came out looking much better than customers who were using Calypso & Geopak/Mcosmos. Being a newbie in the CMM world I didn't know much what went on but wat I was told later that in the end when those guys programmed using legacy the results were within .0003 or so between Calypso & Geopak/Mcosmos. And from that point on they almost always programmed using legacy.
