This architectural drawing is the 2D design of a longitudinal section of the lower level of the earthwork in detail AutoCAD drawing, CAD file, and dwg file. A longitudinal section, often known as a structure's Side Elevation, is a section taken along a structure's lengthwise dimension. Longitudinal sections of roads, canals, bridges, and other structures can be used to calculate the theoretical gradient of a planned structure based on current surface conditions.
