WebThe Place Composite Curve tool in the Curves tool box lets you place a complex element that can contain line segments, arcs, and a special type of B-spline curve, a Bézier curve. Bézier curves A Bézier curve is a B-spline curve with the same number of poles as its order. Thus, a fourth-order B-spline with four poles is a fourth-order Bézier curve. WebHorizontal curves occur frequently as the alignment of roads and highways move through hilly country, along winding rivers, or around obstacles that cannot be moved.
