Usually one sets units to what is better for the drawing, mm for mechanical, m for architecture, foot or inches if in USA,
then draws unscaled, a wall of 7 meters will be a line of 7 units, a side of a piece of 7 milimeters will be a line of 7 units if the units are meters and milimeters respectively.

Later comes the history of putting the drawing into paper...
