Why can I not get an X,Y,Z measurement of 2 parts that intersect. Particularly I want to know how far they intersect so I can make a change instead of always guessing or making special sketches to get a measurement that should be given to me when I measure. I have tried edges, points, faces and only points give me a round about idea, but when there are no points to work with it makes it very hard. See the below image:

I tried the point option in the measure tool and that rarely works for what I am after.

Thanks,
