Object to Extend
Specifies the objects to extend. Press Enter to end the command.
Shift-Select to Trim
Trims the selected objects to the nearest boundary rather than extending
them. This is an easy method to switch between trimming and extending.
Fence
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.
Crossing
Selects objects within and crossing a rectangular area defined by two points.
NOTE Some crossing selections of objects to be extended are ambiguous. EXTEND
resolves the selection by following along the rectangular crossing window in a
clockwise direction from the first point to the first object encountered.
Project
Specifies the projection method used when extending objects.
None Specifies no projection. Only objects that intersect with the boundary
edge in 3D space are extended.
