Conceptual Grading You can easily add conceptual slopes and elevation to your models. By adding grade and elevation, you help communicate the spatial relationships and design intent (Fig. 19-32 through Fig. 19-37). For a review of conceptual grading, see Chapter 13. You should add conceptual grades, even minute slopes, where possible. Ideally, adding conceptual grade should be done before the Flatwork Base is populated with site elements.
