Experience Level: Intermediate

Lengthens a line, an arc, a two-dimensional polyline, or a ray to meet another entity. You can use polylines, arcs, circles, ellipses, infinite lines, lines, rays, splines, or viewports in paper space as bounding entities. When you use a two-dimensional polyline as a bounding entity, entities are extended to the center line of the polyline.

 

 

  1. Select the entity you want to use as the bounding entity.
  2. Select the entities you want to extend.

Result.

Select boundary entities for extend <ENTER to select all>: To select all entities in the drawing, press Enter. Otherwise, select the entity to which you want the second entity extended. After you select the bounding entities, press Enter or right-click the mouse.


NOTE If you press Enter to select all entities in the drawing as boundaries, the program immediately continues to the next prompt.


Edge mode Fence <Select entity to extend>: Select the entity you want to lengthen. To specify that you want an entity to extend to the imagined intersection of two entities (if the two entities do not intersect), choose Edge mode. To extend the entity by selecting fence points, choose Fence.

To extend an entity to an implied intersection

 

 

  1. Select the entity you want to use as the bounding entity.
  2. Select the entities you want to extend.

Result

Choose Edge mode.

Extend No extend <No extend>: To lengthen the entity even if it does not intersect the boundary entity, choose Extend. If you do not want to lengthen the entity if it does not intersect the boundary entity, choose No extend.


NOTE If you select all entities in the drawing as boundaries, selecting Extend may cause an unexpected result.


To extend an entity by selecting fence points

You can extend multiple entities to one entity by selecting fence points.

 

 

Select the boundary entity.

Specify the first fence point.

Specify the second fence point.

Specify the last fence point.

Result

Choose Fence.

First point of fence: Specify the first fence point. A fence point is the beginning point along the entities you want to extend.

Next fence point: Specify the next fence point. You can continue to specify fence points until you have extended all entities. To exit fence mode, press Enter.


TIP To close an arc, use the Arc option of the Circle command.
