Alignment using pattern for rotation

[[Ja...]]

Am I missing something in Calypso? I need to use pattern for rotation only but how?

If you are using the new GD&T engine Datum C would be a Common Datum, you will see the button inside of the feature selection. 

 

If you are creating this via the legacy GD&T engine you will need to create a Bore Pattern Best Fit - when Calypso creates a BPBF it will create a new alignment for you that you can use for other characteristics.

Richard, I'm using the latest version of Calypso and I don't see that option. Am I looking in the wrong place?

Jack,

What do you select when you go to select one of the Datums with the new Engine?

Got it. Was looking in the wrong place. Thanks.
