Additional Extend Options
The
EXTEND
command includes the same Edge, Undo, and
Project
options as the
TRIM
command, and similar rules apply when using these options with the
EXTEND
command. Use the
Extend
mode of the
Edge
option to extend to an implied intersec-
tion, as shown in Figure 11-23. Select the
Undo
option immediately after performing
an unwanted extend to restore previous objects without leaving the command. The
Project
option applies to extending 3D objects, as explained in AutoCAD and Its
Applications—Advanced.
PROFESSIONAL TIP PROFESSIONAL TIP
Figure 11-24 illustrates how to combine the
EXTEND
and
TRIM
commands to draw a wall on a fl oor plan without selecting a boundary
edge. You can apply this process to a variety of applications.
