# Dimension style - radius

**Text before the dimension value (prefix)**: You can insert additional text before each dimension value. For a standard dimension chain this option will only be required in individual cases. In such cases you can also add this prefix using the 'Modify' function for a single dimension chain.

**Text after the dimension value (suffix)**: You can insert additional text after each dimension value. For example, you can place the unit after each number. Note: In architectural dimensioning the unit may change while the suffix remains the same.

**Number of decimal places**: The number of decimal places for the radius dimension.

**Line length of center cross**: If a value greater than 0.000 is entered here, the program creates the dimension arrow so that it ends at the center of the dimensioned circle or arc. At the same time, a small cross with the specified line length is drawn at the center of the circle or arc.

> If, however, the value 0.000 is set here, no center cross is drawn and the dimension arrow is drawn only long enough for the dimension value with prefix and suffix to fit.
