I have a 3D stream feature class. Each vertex has an elevation representing water surface elevation for a 100 year flood. I want to create a new point feature class at the inflection points along the stream profile, where elevation changes by 1ft.

Here is my stream in profile view and some examples of where I want to create points:

My idea is to store the starting value then look at the next vertex, if less than 0.5, skip and move onto the next vertex. Continue this till I hit a vertex that is 0.5 or greater from the starting point. Then create a point at this vertex. Then, move to the next vertex and compare with the last created point.

I'm pretty new to FME, can this be done? Thanks!
