NOTE NOTE
To access the
EXTEND
command while using the
TRIM
command,
after selecting the cutting edge(s), hold down
[Shift]
and pick objects
to extend to the cutting edge. The
EXTEND
command is described
later in this chapter.
Trimming without Selecting a Cutting Edge
To trim objects to the nearest intersection without selecting a cutting edge, access
the
TRIM
command. At the
Select objects or select all:
prompt, press
[Enter]
instead
of picking a cutting edge. Then pick the objects to trim. You can continue selecting
objects to trim without restarting the
TRIM
command. To exit, press [Enter].
Trimming to an Implied Intersection
Use the
Edge
option of the
TRIM
command to trim to an implied intersection. The
No extend
mode is active by default, and does not allow you to trim objects that do not
intersect. To trim nonintersecting objects, access the
TRIM
command, pick the cutting
edges, and select the
Edge
option followed by the
Extend
option. AutoCAD now recog-
nizes implied intersections and allows you to pick objects to trim. See Figure 11-19.
Adjusting the
Edge
mode does not change the selected cutting edges.
Figure 11-17.
The only objects
trimmed with the
Crossing
option are
those that cross the
edges of the crossing
window. Automatic
windowing
accomplishes the
same task.

The
Fence
option allows you to select around objects. In this example, the cutting edge
consists of a rectangle drawn using the
RECTANGLE
command.
