Profile of a Surface error using best fit and common zone.

[[Pa...]]

Hello, I am trying to add a profile of a surface CZ without any base, so best fit should be used:



Unfortunately I am not sure how to do it. I have created a plane using an offset plane, then when I create a characteristic there is no option - without alignment or best fit.



Can you guys help me with this?

If there was a similar topic, sorry for posting this again but the search option is really weak on this forum.

You will need to use Free-Form surface, so that you can select No Datum Reference Frame.
