We're going to delete triangles by using boundaries, and we're going to establish boundaries for our surface, and we're going to look at three different boundary types. Let's open up our exercise file for this video. I'm going to go to the Quick Access Toolbar, choose 04_04_SurfaceBoundary from Chapter Four Exercise Files. And you see four green boundary lines here, three of them are thick, these two in the middle and the outer one wrapping around this way. The one that's not as thick is the current boundary of our surface. Now if we zoom in a little bit on the southwest corner, you see that these spot elevations that are shown, these are the last…
