This architectural drawing is Reinforcement and formwork details of the stairs in AutoCAD 2D drawing, CAD file, and dwg file. A structure called stairs is used to divide a long vertical distance between lower and higher levels into smaller vertical distances. This is done by creating a diagonal row of platforms, known as steps, that are horizontal and provide access to the next level by stepping from one to the next step sequentially.
