Creating the 2′-6″ (762 mm) Interior Opening

The 2′-6″ (762 mm) opening to the bathroom starts 30″ (762 mm) from the
inside of the left exterior wall. You can’t simply offset the wall and trim the
excess because the offset lines would not cross both the interior wall lines.
Instead you will use the EXTEND command exactly as you used it in Chapter 2:
1. Make sure I04-09-7ftExterior.dwg (M04-09-2134mmExterior.dwg)
is open.
2. Start the OFFSET command and offset the interior line of the lowerleft
exterior wall 2′-6″ (762 mm) to the right. Then offset the new line
another 2′-6″ (762 mm) to the right.
3. Start the EXTEND command and then press the spacebar or ↵ to make
every edge in the drawing a boundary edge.

4. Click the two jamb lines to extend them. Be sure to pick points on
the lines that are near the ends that you want to extend, as shown in
Figure 4.33, or the lines will be extended in the opposite direction.
Pick here to extend the lines
to the boundar y edge.

The lines are extended through the interior walls to make the
jambs (see Figure 4.33).

Keeping the EXTEND command active, you’ll use the Shift key to
trim away the excess lines and complete the openings. You’ll do this
by creating two crossing windows—first to trim the excess part of
the jamb lines and then the wall lines between the jamb lines.
5. With the EXTEND command still active, press and hold the Shift key.
Keeping it pressed, select a point to the right side of the bathroom
and then another to the left, as shown in Figure 4.34.

6. Repeat the same process you used in the previous steps. With the
EXTEND command still active, press and hold the Shift key to create a
crossing window through the wall, as shown in Figure 4.35. Press ↵
to exit the EXTEND command

7. Save your drawing as I04-10-30inInterior.dwg (M04-10-
762mmInterior.dwg).
Your cabin should appear as shown in Figure 4.36.
