Extends objects to meet the edges of other objects.
There are two modes that you can use to extend objects, Quick mode and Standard mode.
Quick Mode. To extend objects, select the objects to be extended individually, press and drag to start a freehand selection path, or pick two empty locations to specify a crossing Fence. All objects automatically act as boundary edges.
The Quick mode options are as follows:
Standard Mode. To extend objects, first select the boundaries and press Enter. Then select the objects to be extended. To use all objects as boundaries, press Enter at the first Select Objects prompt.
The Standard mode options are as follows:
The following prompts are displayed either in Quick mode or Standard mode.
Uses the selected objects to define the boundary edges to which you want to extend an object.
Specifies the objects to extend. Press Enter to end the command.
Trims the selected objects to the nearest boundary rather than extending them. This is an easy method to switch between trimming and extending.
Uses the additional selected objects to define the boundary edges to which you want to extend an object.
Selects all objects that cross the selection fence. The selection fence is a series of temporary line segments that you specify with two or more fence points. The selection fence does not form a closed loop.
Selects objects within and crossing a rectangular area defined by two points.
Sets the default extend mode either to Quick, which uses all objects as potential boundary edges, or to Standard, which prompts you to select boundary edges.
Specifies the projection method used when extending objects.
Specifies no projection. Only objects that intersect with the boundary edge in 3D space are extended.
Specifies projection onto the XY plane of the current user coordinate system (UCS). Objects that do not intersect with the boundary objects in 3D space are extended.
Specifies projection along the current view direction.
Extends the object to another object's implied edge, or only to an object that actually intersects it in 3D space.
Extends the boundary object along its natural path to intersect another object or its implied edge in 3D space.
Specifies that the object is to extend only to a boundary object that actually intersects it in 3D space.
