Open Ellipse

Use this function to add an open ellipse by pointing its center point, two radius points in the directions of the main axes, and the starting and end points for the arc. You can select the line properties for an ellipse. When adding an ellipse, you can use auxiliary functions to draw the ellipse in relation to certain line elements.

1. Select Lines> Add open ellipse.
2. Select the line properties.
3. Click a center point (1).
4. Click two radius points (2)(3) in the direction of the main axes so that the axes are perpendicular to each other.
5. Click the starting point (4) of the open ellipse.
6. Click the end point (5) of the open ellipse. The ellipse will be drawn counter-clockwise between the starting and end points when you click the radius points counter-clockwise.

Click the points in a clockwise direction. Compare with the top picture.
