Circle Arc > Perpendicular Append (Temporary Objects Menu)

This command is used to create a Temporary Object as a circle arc which runs perpendicular to a line, a circle arc, an ellipse arc, or a Bézier curve.

The end point of the arc can be entered by clicking the mouse anywhere in the drawing. A circle arc is drawn from this position that ends perpendicularly 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.
