Stacked text is text or fractions aligned vertically.
AutoCAD LT uses the special characters slash (/) and caret (^) to indicate where selected text should be stacked. By default, stacked characters are vertically aligned at the midpoint of the text that precedes them. Enter 054^057 to stack text as shown in the first example. Enter 1/2 to stack fractions as shown in the second example.
Text stacked in the text editor is always aligned with the text baseline.
