Position/ISO/New GD&T

Hi,

I have this on the drawing!

Feature is plane from 18 points and A-A is plane from 16 points.

 

 

 

 

This is how I evaluate it, would it be right way?

How to evaluate this with New GD&T?

I would evaluate it as surface profile, but you did it correctly.

It should be "PlaneRoot" from 18x planes and A-A should be tangential element, which should be by default once applied here as datum.

Thanks,

I have another question, here I should use inner tangential for A-A?

I am curious how you want to measure this, but your only option here is either make many lines and do tangential feature ( radius between lines ) or curves.

Then form a plane from each circle's center. But still it should be tangential element - in this case vector of that plane should be outwards from material.
