An engineering drawing is a type of technical drawing that is used to convey information about an object. Two other common symbols in engineering drawings include R, for the radius of an arc or a circle (sometimes rendered as CR for “controlled radius”) and D, diameter of a circle, sometimes also abbreviated DIA or ø. Radius is the distance from the centre point of a circle to the circumference of a circle. The ALL AROUND symbol was introduced in ASME Y14.5 in 1982 to apply to Profile of a Surface tolerance.
