R.F. stands for "Representative Fraction" in relation to scales. It is a numerical ratio that represents the proportion between the dimensions shown on an engineering drawing and the actual dimensions of the object being depicted. For example, an R.F. of 1:100 means that one unit of measurement on tRead more
R.F. stands for “Representative Fraction” in relation to scales. It is a numerical ratio that represents the proportion between the dimensions shown on an engineering drawing and the actual dimensions of the object being depicted. For example, an R.F. of 1:100 means that one unit of measurement on the drawing represents 100 units in real life. R.F. allows engineers to accurately scale down or enlarge drawings while maintaining proportional relationships between different elements.
