Setting Up a Drawing - AutoCAD 2011 and AutoCAD LT 2011: No Experience Required - page 87

6. The Snap On and Grid On check boxes at the top of the dialog box
should be selected. If they aren't, click them. Your Snap And Grid
tab should look like Figure 3.12.
7. Click OK. The new 2 ′ (1000 mm) grid is now visible. Move the cursor
around on the grid — be sure Snap is on. (Check the Snap Mode but-
ton on the status bar; it's pressed when Snap is on.) Notice the coor-
dinate readout. It's displaying coordinates to the nearest 6 ″ (50 mm)
to conform to the new 6 ″ (50) snap spacing. The cursor stops at sev-
eral snap points between each grid dot.
8. Move the crosshair cursor to the upper-right corner of the grid and
check the coordinate readout. It should display 60 ′ -0 ″ , 40 ′ -0 ″ , 0 ′ -0 ″
(18000.0000, 12000.0000, 0). (In AutoCAD LT, you won't have the
third coordinate.)
Drawing with Grid and Snap
Your drawing area now has the proper settings and is zoomed to a convenient
magnification. You're ready to draw the first lines of the cabin:
1. When the command window displays the Command: prompt, start the
LINE command. From the Home tab ➢ Draw panel, click the Line button
or enter L ↵ . Enter 8',8' ↵ ( 2500,2500 ↵ ), or move the cursor until the
Dynamic Input fields indicate the cursor is over the 8',8' ( 2500,2500 )
point and then click to define the starting point of the line.
2. Hold the crosshair cursor above and to the right of the point you just
picked. AutoCAD shows ghosted linear and angular dimensions that
dynamically display the length and angle of the first line segment as
the cursor moves, and a tooltip window displays the current prompt
for the LINE command (see Figure 3.13).
3. Don't click yet. Hold the crosshair cursor directly out to the right of
the first point picked and note how the linear dimension displays a
distance in 6 ″ (50 mm) increments. The angular dimension should
have an angle of 0.00°, as shown in Figure 3.14.
4. Continue moving the crosshair cursor left or right until the dashed
linear dimension displays 28 ′ (8550). At this point, click the left mouse
button to draw the first line of the cabin wall (see Figure 3.15).
