In the Label Style Composer dialog box, click the Layout tab.
Select a component from the Component Name list.

In the Text Component Editor dialog box, click the Format tab.
In the Text Component Editor window, enter the text you want to stack separated by one of the following characters:
Slash (/) stacks text vertically, separated by a horizontal line.
Pound sign (#) stacks text diagonally, separated by a diagonal line.
Carat (^) creates a tolerance stack, which is not separated by a line.
For example, if you want to create a fraction of 1 over 2, enter 1/2.
In the Text Component Editor window, select the text that you want to stack, and then click on the Format tab.
Note: If you enter numbers separated by stack characters and then either enter a nonnumeric character or press Spacebar or Enter, the Multiline Text - AutoStack Properties dialog box is displayed. In the Multiline Text - AutoStack Properties dialog box, you can select to automatically stack numbers (not nonnumeric text) and to remove leading blanks. You can also specify whether the slash character creates a diagonal fraction or creates a vertical fraction. If you do not want to use AutoStack, click Cancel to exit the dialog box.
To unstack text, select it and click again.
To edit stacked text properties, select the stacked text, right-click, and click Properties to display the AutoCAD Stack Properties dialog box.
You can edit the upper and lower text separately. The Appearance options control the stack style, position, and text size of the stacked text.
