Drawing elliptical arcs

 

An elliptical arc is a portion of an ellipse. The default method for drawing an elliptical

arc is to specify the endpoints of one axis of the ellipse, and then specify a distance

representing half the length of the second axis. Then you specify the start and

end angles for the arc, measured from the center of the ellipse in relation to its major

axis. You can draw elliptical arcs using any of the following methods:

 

• Axis-Axis

• Axis-Rotation

• Center-Axes

• Center-Rotation

 

 

To draw an elliptical arc by specifying the axis endpoints

1 Do one of the following to choose Elliptical Arc Axis-Axis ( ):

   • On the ribbon, choose Home > Elliptical Arc Axis-Axis or choose Draw > Elliptical

     Arc Axis-Axis.

   • On the menu, choose Draw > Elliptical Arc > Elliptical Arc Axis-Axis.

   • On the Draw toolbar, click the Elliptical Arc Axis-Axis tool.

   • Type ellipse and then press Enter, and then type a (for Arc) and press Enter.

2 Specify the first endpoint.

3 Specify the second endpoint.

4 Specify the half-length of the other axis.

5 Specify the start angle of the arc.

6 Specify the end angle.

 

CAD.direct 2019 draws elliptical arcs in the direction you specify.

Go to Tools > Drawing Settings > Drawing Units tab. Under Change Settings For,

select Angular Units. The default setting is counterclockwise.
