Linear vs logarithmic scales. 1  Human hearing is better measured on a logarithmic scale than a linear scale. 2  On a linear scale, a change between two values is perceived on the basis of the difference between the values.  On a logarithmic scale, a change between two values is perceived on the basis of the ratio of the two values.
Reference Scale (M:R Scale) It is the ratio of master units in the active model to the master units in reference model. When sheet is at full scale (Full Size 1=1) and the design model is being scaled down, it is important to scale it by appropriate reference scale factor so as to fit within sheet boundary.
