Autodesk created the hatch patterns whose names begin with
AR-
particularly
for use in architectural drawings, and unlike the non-AR patterns, they
do
repres-
ent real objects such as brick and roof shakes. The AR-patterns were designed
with a final hatch scale of 1.0 in mind, but in some cases, you'll have to adjust up
or down in order to achieve a suitable scale.
Hatching for the 21st century
With annotative hatching, you start with the paper scale (because that's where all your
fancy CAD geometry is going to end up) of 1:1. Once again, most patterns look better at
between half and three-quarters of the paper scale, so try setting the hatch scale to, say,
0.75. The following steps explain how to create annotative hatching:

The drawing named
afd15a.dwg
contains the architectural detail shown in Fig-
ure 15-6.
1. Open a drawing containing geometry that forms fully closed boundaries, or
draw some boundaries by using the drawing commands described in Chapters 8
and 9.
The areas you want to hatch should be completely enclosed. The CIRCLE,
POLYGON, and RECTANG commands, and the LINE and PLINE commands with the
Close option, make great hatch boundaries (see Chapters 8 and 9 for details).
2. Set an appropriate layer current, as described in Chapter 6.
3. Start the HATCH command by typing
H
and pressing Enter. Alternatively, click
the Hatch button on the Draw panel of the Ribbon's Home tab.
AutoCAD prompts:
Pick internal point of [Select objects/seTtings]:
4. Type
T
to select the
seTtings
option and press Enter.
The Hatch and Gradient dialog box as seen in Figure 15-4 appears.
5. Choose Predefined, User Defined, or Custom from the Type drop-down list.
Predefined works best for most purposes. See the “Hatch from scratch” section,
earlier in this chapter, for details.
