[Ia...] Posted May 22, 2020 Share Posted May 22, 2020 Flag Note 4: "Datum A to consist of the inside surface, including the radius and flats". I don't know how to make this a feature that can be used as a datum within Calypso.

[Cl...] Posted May 22, 2020 Share Posted May 22, 2020 Just the surfaces shown? I'm assuming that -A- is primary? My first thought was to use that longer straight edge on the bottom as a planar rotation, then translate to the center of the radius?

[Ia...] Posted May 22, 2020 Author Share Posted May 22, 2020 So do you think it should control just one translation? Link to comment https://qualityforum.zeiss.com/topic/15700-how-would-you-capture-this-datum/#findComment-85512 Share on other sites More sharing options...
[Ke...] Posted May 22, 2020 Share Posted May 22, 2020 Please sign in to view this quote. How is the datum applied? (to what features/orientations)?

[Ia...] Posted May 23, 2020 Author Share Posted May 23, 2020 Please sign in to view this quote. It applies to all profiles and all holes along the entirety of the part, which are on the radius, and both flats. A is primary datum in all control frames. I guess this brings up a different question. Using the can may must rule, if it CAN and may constrain them, it has to right? Or would basic dimensions override that?

[Da...] Posted May 25, 2020 Share Posted May 25, 2020 Unless it has from A--B or something like that it is only the Plane Not the entire surfaceCapture.JPG Link to comment https://qualityforum.zeiss.com/topic/15700-how-would-you-capture-this-datum/#findComment-85518 Share on other sites More sharing options...
[Da...] Posted May 25, 2020 Share Posted May 25, 2020 I'm Guessing Note 4 is the defining the Datum? I would use a profile scan make it best fit from the two planes with Rotation and translation. Then use that Best fit alignment to check the other features. I will try it tomorrow when I have time. Send Screenshots.
