Equal Grid Across Surfaces

This is a very clean approach. It works great for simple extrusions. Unfortunately, the application that I’m working up to has a more uneven surface (I reduced it to simplest terms in my original question to help me understand the approach). When the surface is broken or uneven, the contour approach doesn’t keep the columns of points aligned so it doesn’t form a perfect grid.

Thanks, I appreciate all the input on this project!
