## Function Description:
This command is used to create a radius dimension for a circle or an arc. Measures the radius of a selected circle or arc and displays the dimension text with a radius symbol in front of it. You can use grips to reposition the resulting radius dimension easily.
## Command Access:

## Command Prompts:
```
Select arc or circle:
Specify dimension line location or [Mtext/Text/Angle]:
```
## **Select arc or circle**
Specifies a circle, arc or arc segment on a polyline.
## **Dimension line location**
Determines the angle of the dimension line and the location of the dimension text. If the dimension is placed off of an arc resulting in the dimension pointing outside the arc, the product automatically draws an arc extension line.
## **Mtext**
Edits the dimension text by In-place Text Editor. Users can enter special characters and symbols by control codes or Unicode character strings.
If alternate units are not turned on in the dimension style, users can enter square brackets ([]) to display them.
The current dimension style determines the appearance of the generated measurements.
## **Text**
Customizes the dimension text at the Command prompt.
The generated dimension measurement is displayed in angle brackets (<>). If alternate units are not turned on in the dimension style, users can enter square brackets ([]) to display them.
User can reset the dimension text properties in Text tab of the New, Modify, and Override in Dimension Style Manager dialog box.
## **Angle**
Changes the angle of the dimension text.
