<p>This Architectural Drawing is AutoCAD 2d drawing of Side sectional elevation of an industrial plant. 2D sections and elevations define the 2D representation of orthogonal views of a 3D building model. They are not geometric objects in and of themselves, but are more of a “report” of the model. One particularly useful type of drawing is what's called an architectural “section.” It's the drawing of a vertical cut through a building or an area of a building. The purpose of a section is to show, graphically, the main volumes of the building and the main building material components. For more details and information download the drawing file.</p>
