Working with Hatches, Gradients, and Tool Palettes - AutoCAD 2011 and AutoCAD LT 2011: No Experience Required - page 574

You can use the header lines to help form a boundary line across
an entryway to a room and to keep the hatch pattern from extending
to another room.
2. With the floor plan in full view, freeze the A- ROOF and A-ANNO-TEXT
layers and then zoom into the bathroom.
Even if the rooflines are dashed, they will still form a boundary to
a hatch.
3. Create a new layer called A-FLOR-PATT . Assign it color 142, and make
it current.
4. Start the HATCH command to load the contextual Hatch Creation tab.
5. Change the Hatch Type to User Defined from the drop-down on the
Properties panel of the contextual Hatch Creation tab.
After you choose User Defined as the Hatch Type, USER is selected
as the current pattern in the Pattern panel, and the Scale text box in
the Properties panel is replaced by the Hatch Spacing text box.
6. In the Hatch Spacing text box, change 1 ″ (1) to 9 ″ ( 229 ). Next, expand
the Properties panel and click the Double button (see Figure 11.18)
FiGuRE 11.18 Defining the hatch pattern
7. Back in the drawing, be sure no osnaps are running, and use the auto-
matic preview to pick two points to match the tiled hatch pattern shown
in Figure 11.19.
For the first point, pick a location in the bathroom floor area, not
touching the fixture lines or the door. To finish the bathroom floor
hatch, click the floor between the door swing and the door, being
careful to not touch the door.
8. With the bathroom hatches in place, press ↵ to end the HATCH command.
The tiled hatch pattern should fill the bathroom floor and stop at the
header while not encroaching into the door or fixtures (see Figure 11.19).
