‘Scaling For Height’ option adjusts the height of tolerance number in dimensions with scale factor according to the height of primary dimensions.

You can adjust the placement of tolerance and zero suppression of your tolerance values as shown in the orange box. For example, your tolerance dimension is 0.005, if you select the ‘Leading’ option, this value will be suppressed as .005. If you select the ‘Trailing’ option, 0.05000 will be suppressed as 0.05.

Like alternate units for primary dimensions, you can also adjust alternate tolerance units as shown in a red box above.
