Arc dimension

• Radius
• Diameter
• Diameter in a given angle
• Arc length

You can choose from several scaling options when sizing the circular arcs.

Command location: Annotate > Arc

Radius

This command creates the radius dimensioning of a circle or an arc of a circle. The dimension line can be placed either outside or inside the circle. If it is inside the circle its starting point is the centre of the circle and the text is placed at the middle of the radius. If the dimension line is placed outside the circle, the text is put where you click on.

Diameter

The command creates the diameter dimensioning of a circle. The dimension line crosses the centre point of the circle and the specified point. The text can be placed either outside or inside the circle. If the dimension line is outside the circle, the text is placed where you click on; otherwise it is placed at the middle of the diameter.

Diameter in a given angle

The command creates the diameter dimensioning of a circle as well. Here you have to specify the angle of the dimension line (and the positive X axis). The dimensioning can be placed both outside and inside the circle.

Arc length

The command creates the arc length dimensioning of a circle or arc as well. In the Dimension properties dialog you can set the Shape of arch length dimension. The arc’s extension line to be radial or extension-directed in case of central angles under 90 degrees.
