Ellipse Arc > Rectangular (Draw Menu)

This command draws a rectangular ellipse arc. "Rectangular" means here that both half-axes of the underling ellipse are at right angles to one another. With this command they are in addition horizontal and vertical. Horizontal and vertical refer to the position relative to the view. If the drawing is displayed rotated then the half axes are created correspondingly rotated.

1.	Enter center point

The center point of the ellipse can be entered with the mouse by clicking anywhere in the drawing.

2.	Enter point on frame

The point on the frame surrounding the ellipse can be entered with the mouse by clicking anywhere in the drawing.

3.	Enter start angle

The start angle of the ellipse arc can be entered with the mouse by clicking anywhere in the drawing. The position of this point relative to the center determines the start angle.

4.	Enter end angle

The end angle of the ellipse arc can be entered with the mouse by clicking anywhere in the drawing. The position of this point relative to the center determines the end angle.

The appearance of the ellipse arc is determined by the current arc direction setting. This is set using the command Toggle Arc Direction (F2), with the F2 key or the button in the panel. If the arc direction is positive, the ellipse arc is drawn in a mathematically positive (i.e. anti-clockwise) direction from the start angle to the end angle. If the arc direction is negative, the ellipse arc is drawn in a mathematically negative (i.e. clockwise) direction from the start angle to the end angle (see graphic).

The resulting ellipse arc is shown during entry and changes immediately if the current arc direction is changed during entry.

A rectangular ellipse arc is stored as a distorted ellipse arc. It can therefore be further rotated or distorted later.

The ellipse arc is assigned to the current layer. In addition, it contains a reference to the current pen.

The arc direction settings saved in an ellipse arc are not affected by changing the current arc direction. To change the arc direction of an existing arc, use the command Transform Object to > Invert.
