[Sh...] Posted August 12, 2019 Share Posted August 12, 2019 Hello, I am having difficulty with measuring a profile of a radius of an off set bore Datum C is the maximum diameter of the bore with three different lobes.

[Ri...] Posted August 12, 2019 Share Posted August 12, 2019 Calypso really likes having a fully defined DRF. Either use Free-Form and create an alignment using Best-Fit, or fill in Datum D as your Tertiary Datum. Datum C is Primary, Datum D is Secondary and Tertiary. It should work correctly then.

[Sh...] Posted August 14, 2019 Author Share Posted August 14, 2019 Would datum D then be a line thru ID and .187 Radius? Link to comment https://qualityforum.zeiss.com/topic/18008-profile-of-lobe-_-cylinder/#findComment-101210 Share on other sites More sharing options...
