Further exploration: For Component 1, in the Slope Line section, change Percent Of Length to a higher value. You can see the results in the Preview pane. 10 Click OK. The new Ditch Slope pattern is selected for the Ditch grading style. 11 To view summary information about the style, click the Summary tab. 12 Click OK. In Toolspace, on the Settings tab, the Ditch grading style is added to the Grading Styles collection. The Ditch Slope pattern is added to the General ➤ Multipurpose Styles ➤ Slope Pattern Styles collection. To continue to the next tutorial, go to Creating Gradings (page 392). Tutorial: Creating Gradings This tutorial demonstrates how to create a feature line and how to grade from the feature line. You can create gradings from parcel lot lines or feature lines. A feature line is a linear object that the grading commands can recognize and use as a baseline. When designing a grading, you must often adjust the elevations along a feature line. You create a feature line by converting existing objects, such as lines or polylines. In the next two exercises, you will perform the following tasks: ■ Create three feature lines. ■ Assign elevation values along the feature lines using several methods. ■ Create a set of gradings from one of the feature lines. For more information, see the AutoCAD Civil 3D Help topic Creating Grading. Exercise 1: Creating Feature Lines In this exercise, you will use two different methods to create feature lines. Feature lines can be either drawn with straight and curved feature line segments, or created from existing alignments or AutoCAD lines, arcs, polylines, or 3D polylines. 392 | Chapter 11 Grading Tutorials
