1. Click the Undo button on the Quick Access toolbar, enter U ↵ at the
command line, or use the standard Windows keyboard shortcut
Ctrl+Z.
The counter you just drew should disappear. If you ended the LINE
command while drawing the counter and had to restart it before you
finished, you might have to click the Undo button more than once.
If you undo too much, click the Redo button, which is just to the
right of Undo.
Now, you'll draw the counter again, this time using the OFFSET and
FILLET commands.
2. Offset both the left inside wall line and the top inside wall line 2 ″ (610
mm) to the inside of the cabin.
3. Stop and then restart the OFFSET command. This time, offset the
inside left wall line 7 ′ -1 ″ (2159 mm) to the right.
4. Next, offset the inside top wall line 6 ′ -0 ″ (1829 mm) (the sum of the
two counter dimensions and the stove dimension) downward (see
Figure 5.44).

TIP as discussed earlier, if the FILLET command has a nonzero radius
setting that you want to keep, hold down the Shift key to set the radius to
zero for one use of the command. after the command ends, the radius returns
to its nonzero setting.
5. Use the FILLET command with a radius of zero to clean up the three cor-
ners. Be sure to click on the portions of the lines that you want to retain.
