This architectural drawing is the 2D design of a cross-section of the staircase in detail AutoCAD drawing, CAD file, and dwg file. Stairs are primarily used to give a quick and convenient way to transition between floors. In the past, buildings and shelters had just one story, but it was later realized that by using the space above the ground, a construction could provide more room.
