Construction Aid Circle Arc > Tangential Append (Construct Menu)

This command draws a Construction Aid circle arc which runs tangential to a line, a circle arc, an ellipse arc, or a Bézier curve.

The end point of the Construction Aid arc can be entered by clicking the mouse anywhere in the drawing. A circle arc is drawn from this position that ends tangentially at the reference object.

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.

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