Slopes and Grades The tutorial will teach you how to use arcs and edges drafted on a vertical surface to generate a series of gentle slopes and grades. Make sure the arcs are flush with vertical face of the walls. Download from 3D Warehouse and open model: Slopes_Grades 1. Draw three connected arcs along the vertical surface of the wall as shown in the graphic.
Make sure to connect the first point of the first arc and the second point of the third arc to the bottom corner endpoints of the wall and Flatwork Base. Select the three drawn arcs and the arcs that compose the adjacent edge of the trail. With all the edges selected, activate the From Contour tool.
