Extend a line or arc to the first intersecting point or bounding geometry. If no intersection or bounding geometry is found, then the line or arc ends at the release point.

Shortcut: x

  1. Click Extend tool icon.
  2. Click the line or arc to extend.
  3. Click new location for the end, or extend to the bounding geometry location (a point or edge, for example).

Alternatively, double-click the arc edge, or select and drag the arc edge to auto-complete the arc by extending it to the bounding geometry. In the example below, the ellipse is completed.
