8 In the Grading Elevation Editor, in the value to 400.00'. row, change the Elevation 9 In the right viewport, select feature line ABC. Using the grip inside Circle A, move the beginning point of the feature line toward the lower left of Circle A. NOTE You may need to hover over the feature line, and then use Shift+spacebar to select the feature line. 10 Right-click the feature line. Select Elevation Editor. In the Grading Elevation Editor, the icon indicates the point at which the feature line crosses the building pad. The white triangle indicates a split point, which is created when two feature lines cross at a location where neither one has a PI. Much like a shared vertex point, a split point acquires the elevation of the feature line that was most recently edited. If the other feature line has a different elevation, it gets a grade break at the crossing point. Unlike a shared vertex, there is not an actual point at a split point, so you cannot directly edit the elevation. When you edit one of the feature lines, its grade runs straight through the intersection, forcing the other feature line to break at the split point. You can use the Insert PI command to create a permanent point at that location on one of the feature lines. After you convert a split point to a permanent point, you can edit the elevation of a split point directly, and have better control over that point. 11 Select the grip at the beginning point of the feature line. On the command line, enter END to apply an endpoint OSNAP. Snap the feature line to the building pad feature line. Notice that an elevation change point with an elevation of 402.000' was added in the second row. The change point was added because you changed the elevation of the endpoint (the shared vertex) of this feature line to 402.000' in step 4. When you changed the elevation of the shared vertex on the building pad feature line to 400.000' in step 8, the grade break point was created. The grade break point ensures that the elevation of this feature line would match the elevation of the building pad. 12 In the Grading Elevation Editor, click Elevations. .
