Drape a feature line on a surface 1 If necessary, press Esc once or twice to deselect feature line AB. 2 Click Modify tab ➤ Edit Elevations panel ➤ Elevations From Surface. 3 In the Set Elevations From Surface dialog box, click OK. 4 Click feature line BC, then right-click and click Enter to end the command. 5 Click feature line BC again. An elevation point has been added wherever the line crosses the edge of a triangle in the TIN surface. 6 Right click and click Elevation Editor. The Elevation Editor displays data for each elevation point along feature line BC, including its elevation, and the distance and grade to the next point. A feature line on the surface like this can be a useful starting point for a grading. You can use controls along the top of the Grading Elevation Editor to add and delete elevation points, and to adjust their elevations. You can select multiple points within the table for group operations, such as raising or lowering them the same amount, or "flattening" their elevations to the same value. 7 Click to close the Grading Elevation Editor. To continue this tutorial, go to Exercise 3: Creating a Grading (page 397). Exercise 3: Creating a Grading In this exercise, you will create a set of gradings, called a grading group, that form a runoff on the side of an embankment. For more information, see the AutoCAD Civil 3D Help topic Creating Grading from a Footprint. This exercise continues from Exercise 2: Assigning Feature Line Elevations (page 395).
