This determines the range of the CAD GD&T Font Size slider on the Font Setup dialog box. It limits how many values the slider can move to.
The value is the number of increments above and below the midpoint of the slider. So, a value of 4 allows four increments above and below the mid point.
Each increment increases or decreases the font slider by 10%.
