Hello,

The term R.F. is a ratio of size taken on drawing sheet to the actual size of the object. These are used mainly in Civil layout and plans to make that drawings in standard sheet of A0 to A4.

R.F (Representative factor) is defined as the ratio of size of drawing to the size of actual element.

Thank you

Hey Harvansh, I am javed.
R.F. is the ratio of drawing size to actual size of the object or component. When drawing size is equal to the object size. Than the R.F. is 1:1. Which is basically used in automotive industry. And when drawing size is more as compared to the object.It means our object is small. Which is used in small component like watch. And when drawing size is less as compared to the object. It means our object is big. Which is basically used in the civil industry.

I hope. It is helpful for you.
