I am measuring a part that has .003" material left on the top (orange surface in photo) for grinding stock.

The points you see going around the threads I am trying to measure the T-Value of to see how much more we need to EDM off of them.

So in the point feature window, should I set my T value to THEO or ACTL to account for the grind stock? The threads are tapered at a 45° angle, so I am assuming the T-Value should also be .0021 and not .0030?
