Extend

The Extend tool is used to extend any line or arc segment with a specified distance or until it intersects with another entity.

To extend an entity by a specific distance, select the Extend tool and then type in the distance value in the input. After entering the distance, click on the entity you want to extend.

To extend an entity until it intersects with another entity, select the Extend tool and click on the entity you want to extend. The entity will be extended until it meets the nearest intersecting entity.

The Extend tool can also be used to connect two lines. To do this, select the Extend tool, click on the first line, and then click on the second line you want to connect it to. The first line will extend until it intersects with the second line. Click on the second line to complete the operation.
