This Architectural Drawing is AutoCAD 2d drawing of Section Marking plan and elevation Drawing. Plan drawings are in fact a type of section, but they cut through the building on a horizontal rather than vertical plane. The direction of the plane through which the section is cut is often represented on plan drawings and elevations by a line of long and short dashes, called a section plane. In basic terms, a plan is a birds-eye view of a space. When drawing a floor plan, the roof would be removed so the interior space can be seen. This is an elevation view. An elevation is a view from the side of an object, when drawing interior elevations, this would represent one of the walls. For more details and information download the drawing file.
