PROFESSIONAL TIP P R OFESSIONAL TIP
Objects often do not align conveniently for using crossing selection to pick objects to
stretch. Consider using a crossing lasso or crossing polygon to make selection easier. If
the stretch is not as expected, press
[Esc]
to cancel. The
STRETCH
command and other
editing commands work well with polar tracking or
Ortho
mode.

Using the LENGTHEN Command U s ing the LENGTHEN Comm a nd
Use the
LENGTHEN
command to change the length of a line, arc, polyline, spline, or
elliptical arc, or the included angle of an arc. You can only lengthen one object at a time.
You cannot lengthen a closed object because an unconnected endpoint does not exist.
Access the
LENGTHEN
command and select the object to change. AutoCAD identifi es
the current length. If the selected object is an arc, the length and included angle are iden-
tifi ed. The initial selection is for reference only. Select an option and follow the prompts
to complete the operation. Preview the operation before completing the command.
