AutoCAD objects are created from each of the watersheds in the drawing. 5 In the drawing, click inside a watershed area. A blue grip appears inside the area, indicating that you have selected an AutoCAD object. 6 On the command line, enter List. The AutoCAD text window displays parameters for the object you selected. You can use any of the standard AutoCAD commands to modify or query the new object. To continue this tutorial, go to Exercise 5: Analyzing Surface Water Runoff (page 101). Exercise 5: Analyzing Surface Water Runoff In this exercise, you will create lines that illustrate the path that flowing water would take across a surface. Then, you will create a polygon that defines the catchment region and its area on the surface. The water drop utility creates either a 2D or 3D polyline object that runs downhill on a surface from any point you select. You can specify whether the point you select is indicated with a marker. After the lines are created, you can edit or modify them as needed. You can use the information you get from the water drop analysis to calculate catchment areas, based on specified low points of the surface. The catchment regions can be created on the surface as either 2D or 3D polygons, which can be exported to a hydrology application for detailed analysis. For more information, see the AutoCAD Civil 3D Help topics Drawing Water Drop Paths and Displaying and Calculating Catchment Areas. This exercise uses a drawing file similar to the one used in Exercise 3: Creating a Watershed Legend (page 99). The surface style is changed to make it easier to see the basic surface features, and it contains a simple point style for you to use as a start point marker. This exercise continues from Exercise 4: Extracting Objects from a Surface (page 100). Perform a water drop analysis 1 Open Surface-5C.dwg, which is located in the tutorial drawings folder (page 819). Exercise 5: Analyzing Surface Water Runoff | 101
