## Description

The **extend edge** tool extends an edge to an arbitrary location in the sketch, or to a target edge or point object.

Shown on the left (1), the two sketch elements before the operation; in the middle (2), the line is being extended to the arc; to the right (3), the final result.

## Usage

- Press the Extend edge button.
- Select a line or an arc.
- In the 3D view, move the mouse pointer toward the direction to extend.
- Click on an arbitrary location in space, or
- To extend to another edge, place the mouse pointer over the target edge; when it is highlighted and the Point on object constraint icon appears besides the mouse pointer, click to confirm. A point on object constraint will be added.
- To extend to a point in the sketch, place the mouse pointer over the target point; when it is highlighted and the Coincident constraint icon appears besides the mouse pointer, click to confirm. A coincident constraint will be added.

## Notes

- Only arcs and lines can be extended at this time.
- The target edge or point object may be modified as well if it is not fully constrained.
