To do this trim efficiently, you need a closer view of the T-intersections. Use the
ZOOM command to get a better look:
1. Make sure I04-05-WallCleanUp.dwg (M04-05-WallCleanUp.dwg)
2. Type Z↵. Then move the crosshair cursor to a point slightly below
and to the left of the upper T-intersection (see Figure 4.19), and click
in a blank area outside the floor plan.
F igu re 4 . 1 9 : Positioning the cursor for the first click of the ZOOM command
3. Move the cursor up and to the right, and notice that a rectangle with
solid lines is being drawn. Keep moving the cursor up and to the
right until the rectangle encloses the upper T-intersection (see the
top of Figure 4.20).
F igu re 4 . 2 0 : Using the Zoom Window option: positioning the rectangle
(top) and the new view after the ZOOM command (bottom)
When the rectangle fully encloses the T-intersection, click again.
The view changes to a closer view of the intersection of the interior
and exterior walls (see the bottom of Figure 4.20
The rectangle you’ve just specified is called a zoom window. The
area of the drawing enclosed by the zoom window becomes the view
on the screen. This is one of several zoom options for changing the
magnification of the view. Other zoom options are introduced later
in this chapter and throughout the book.
4. In the Home tab ➢ Modify panel, click the Extend button.
In the command-line interface, notice the second and third lines of
text. You’re being prompted to select boundary edges (objects to use
as limits for the lines you want to extend/trim).
5. Select the two horizontal interior wall lines, and press the spacebar or ↵.
The prompt changes and asks you to select the objects to be extended.
6. Press and hold the Shift key while you select the inside exterior wall
line at the T-intersection that is between the two intersections with
the interior wall lines that you have just picked as boundary edges
(see the top of Figure 4.21).
F igu re 4 . 2 1 : Selecting a line to be trimmed (top) and the result of the
EXTEND command used in conjunction with the Shift key (bottom)
The exterior wall line is trimmed at the T-intersection (see the
bottom image of Figure 4.21). Press the spacebar to end the EXTEND
7. Return to a view of the whole drawing by typing Z↵ and then P↵.
This is the ZOOM command’s Previous option, which restores the
view that was active before the last use of the ZOOM command (see
Figure 4.22). This command is also available from the Zoom flyout
on the Navigation bar.
F igu re 4 . 2 2 : The result of the Zoom Previous command
Repeat the procedure to trim the lower T-intersection. Follow these steps:
1. Type Z↵, and click two points to make a rectangular zoom window
around the intersection
2. Start the TRIM command, select the interior walls as cutting edges,
and press the spacebar.
3. Select the inside exterior wall line between the cutting edges.
4. Press the spacebar or ↵ to end the TRIM command.
5. Zoom Previous by typing Z↵P↵. Figure 4.23 shows the results.
F igu re 4 . 2 3 : The second trim is completed.
6. Save your drawing as I04-06-ZoomCommand.dwg
You need to create one more set of interior walls to represent the closet in the
upper-right corner of the cabin.
