The position of the text relative to the dimension line is referred to as vertical justification. Text can be placed above or below or centered within the dimension line. In the ANSI standards, centered text usually splits the dimension line. In the ISO standards, it is usually above or outside the dimension line. For example, ISO standards permit angular dimension text to appear in any of the ways shown.
Other settings, such as Inside Horizontal and Outside Horizontal, affect the vertical justification of text. For example, if Inside Horizontal is selected, text inside the extension lines and centered within the dimension line is horizontal, as shown in the leftmost illustration above. The text is horizontal even if the dimension line is not itself horizontal.
If Inside Horizontal is selected, text above the dimension line appears as shown in the following illustrations.
