Creating an existing ground surface

Discover how surfaces in Civil 3D are used when establishing existing conditions in a civil project. Create a representation of the ground in 3D as you create and modify surfaces, and incorporate survey points and 3D polylines into the surface. Learn to work with grid surfaces, created by importing DEM files, as well as breaklines, such as embankments, road edges, and ditches. Once the surface is created, work with the editing tools to fix errors and further refine the surface. Add surface styles, labels, and tables to convey surface information on your design plans, work with volume surfaces for calculating cut and fill, and create boundaries for surfaces.
