Smooth the lot grading surface

“

- [Voiceover] As we've been developing the grading for the lots you may have noticed that the contours appear a bit jagged. Let's see how smoothing can be applied to fix that condition. If I zoom into lots one and two you'll see some of the jagged contour appearance that I was talking about. And this is because the surface is made up of triangles and the contours are generated by interpolating points from a triangle edge to triangle edge. And if I were to turn on the triangles for this surface, which I will, you'll kind of see what I'm talking about. I'll change this to contours and triangles. And if we look at this corner for example you'll see how the triangulation and the edges of the triangles kind of dictate this wavy pattern in the contours. There's really no way around that. But what we can do is minimize the size of those waves in the contours to where they're almost invisible. So let me switch the surface back to the style it was, which was contours one and five design. And…
