Subject: Controlling dimension fit

You can control the way dimension text and arrowheads are placed in relation to the dimension lines. You can also control how the dimension scales by choosing whether it is annotative by default or whether it scales according to a specific scale or accord­ing to the layout. Any changes you make affect the current dimension style. The image tile on the right side of the Dimension Styles dialog box shows the appearance of dimensions based on the current dimension style settings.       

The program determines whether both dimension text and arrowheads will fit between the extension lines by comparing the distance between the extension lines to the size of the dimension text, the size of the arrowheads, and the amount of space required around dimension text. The program applies the best fit method based on the available space. If possible, both the dimension text and arrowheads are placed between the extension lines. If both will not fit between the extension lines, you can determine how text and arrowheads are placed using the Fit Method settings on the Dimension Styles dialog box.
