This Architectural Drawing of AutoCAD 2d drawing is Roof framing plan with slope details. The most commonly used roof pitches fall in a range between 4/12 and 9/12. Pitches lower than 4/12 have a slight angle, and they are defined as low-slope roofs. Pitches of less than 2/12 are considered flat roofs, even though they may be very slightly angled. A roof framing plan is a scaled layout or a diagram of a proposed roof development, including the dimensions of the entire structure, measurements, shape, design, and placement of all the materials, wires, drainage, ventilation, slopes, and more.
