Circle Arc > Diameter (Temporary Objects Menu)

This command is used to create a Temporary Object as a circle arc. The circle arc is calculated by entering two points, one at either end of its diameter, plus start- and end-angle.

If a circle arc is to be drawn while working in isometric or dimetric view, then the command Ellipse Arc > Vector - Vector must be used, because the result on the page is elliptical not circular.

The first point through which the circle should run can be entered by clicking the mouse anywhere within the drawing.

The second point through which the circle should run can be entered by clicking the mouse anywhere within the drawing.

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

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

The resulting arc is affected 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, then the arc is drawn in a mathematically positive direction (i.e. counterclockwise) from the start angle to the end angle. If the arc direction is negative, then the arc is drawn in a mathematically negative direction (i.e. clockwise) from the start angle to the end angle (see graphic).

The resulting arc is shown while it is being entered and changes immediately if the current arc direction is changed.
