Line of Lowest Points on a Surface

[[TH...]]

I have a curved surface seen in the image attached. I want to generate a line/series of points that are the lowest on the surface (lowest Z-locations). I have a symmetric surface on the other side of the part, and would want to do the same thing and then find the widths between each pair of points. 

How can I go about creating these points on the surface? I tried creating equidistant inspection points on the surface which look promising but I can't confirm if they are the lowest points on the surface. 

Any help would be appreciated.

There's a few ways to go about this.

If you have curve:

You can do multiple curves on each surface at the same heights. Then use the minimum/maximum coordinate feature to get the lowest associated point that corresponds with the axis you choose. Then distance those points.

If you don't:

You could use circles at the same heights, then do a caliper distance, toggling between maximum and minimum to suit your needs.
