| 1 | Extends the selected edge to its natural boundary |
Line, arc, elliptical arc, ray, and polyline are eligible objects for natural extension. The natural extension of a line or ray is an unbounded line (xline); an arc is a circle, and an elliptical arc is an ellipse. A polyline is broken down into its line and arc components, which are extended to their natural boundary.
