| Value | Description |
|---|---|
| 0 | Uses the selected edge without any extensions |
| 1 | Extends or trims the selected object to an imaginary extension of the cutting or boundary edge |
Lines, arcs, elliptical arcs, rays, and polylines are objects eligible 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 boundaries.
