## Function Description:
This command is used to create an arc length dimension.
## Command Access:

> **Menu:** Dimension \> Arc Length
> **Ribbon:** Annotation \> Dimension \> Arc Len
> **Toolbar:** Dimension \>
> Arc Len
> **Command:** DIMARC
> **Alias:** DAR
## Command Prompts:
Select arc or polyline arc segment:
Specify arc length dimension location, or \[Mtext/Text/Angle/Partial/Leader\]:
## **Arc or polyline arc segment**
Specifies an arc or a polyline arc segment to be
dimensioned.
## **Arc length dimension location**
Specifies the placement of the dimension line and determines the direction
of the extension lines. Arc length dimensions measure the distance along an arc
or polyline arc segment. The extension lines
of an arc length dimension can be orthogonal or radial. An arc symbol is
displayed either above or preceding the dimension text.
## **Mtext**
Edits the dimension text by In-place Text Editor. Users can enter special characters and symbols by control code 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 New, Modify, and Override in Dimension Style Manager
dialog box.
## **Angle**
Changes the angle of the dimension text.
## **Partial**
Reduces the length of the arc length dimension.
## **Leader**
Adds a leader object. Only if the arc or arc segment is greater than 90
degrees, this option displays. The leader is drawn radially, pointing towards
the center of the arc being dimensioned.
## **No leader**
Cancels the Leader option before creating the leader. To remove a leader,
delete the arc length dimension and recreate a new arc dimension without the leader
option.
