- [Instructor] So far, we've created a surface by adding points using a point group. Those points, of course, were added providing the x, y, and z to create the triangles between the points. What we're going to do now is we're going to try to align those triangles to line up better with our grade breaks and get a more accurate rendering of the existing ground. To do that, let's go ahead and open up our exercise file. It's 03_SurfaceBreaklines. In this drawing, what we've done is we've turned on the TIN, or the triangles, so that they're more visual. You can see how the surface is created. And so what we have is we have our edge of pavement, our centerline, and then we have a top of slope and bottom of slope on all these ends, on all these three sides here of our intersection. And if you notice, here our triangles go across the edge of our pavement. Really, this is what we would call a grade break. The pavement is going to be flat, and then there will be a change of grade between the…
