Hi Brent,
I would like to be able to save the data I enter for saddle reference points (X) and (Y) with the saddle in the standard library.
When modeling saddles I use the parameter A to define where the lowest point of the upper saddle contour is. And I guess that was also your intention. But this is not necessarily the halfway point of the saddle length. When measuring the saddle height in order to get to comparable values it is often recommended to first mark that halfway point on the surface of the saddle and then measure from the center of the bb up to that point.
