Characters representing fractions and tolerances can be formatted to conform to several standards.
Stacked text refers to the fraction and tolerance formats applied to characters within multiline text object and multileaders.
You use special characters to indicate how selected text should be stacked.
By default, numeric characters entered before and after a slash, pound sign, or carat will stack automatically. For example, if you enter 1#3 followed by a nonnumeric character or space, the result is 1/3.
The automatic stacking feature applies only to numeric characters immediately before and after the slash, pound sign, and carat. For tolerance stacking, the +, -, and decimal character also stack automatically.
To change Stack Properties, right-click stacked text and choose Stack Properties.
