I have a rather long part that has a Line Profile specification.

Imagine a banana (keep yer mind outa the gutter graiger).

This banana is positioned with the long axis in Y.The Line Profile is specified in the X axis, in the short, curved direction.

So I measure a series of points all in a row running in line with the X axis.

I create a set of these 12 points.

Dimension the Set Profile of a Line, Form Only, +.010", Bestfit in YPLUS or YMINUS.

I have a series of these lines running the length of the banana.

Due to some deburring irregularities, some of the sets are showing out-of-tolerance.

First problem: graphical analysis has arrows pointing in Y+ and Y-. I expect them to point in Z+ or Z-. I can get them to do that if I change the bestfit to X or Z, but the results are VERY much worse then.

Second problem: When I try to generate a Dimensional info box, I cannot get the deviation values to match the deviation values reported in the textual analysis for the set.

Maybe there is no way to do this?
