A
hatch object displays a standard pattern of lines and dots used
to highlight an area, or to identify a material, such as steel or
concrete. It can also display a solid fill or a gradient fill.
Create hatches and fills with the HATCH command. The
following illustration includes a solid fill, a gradient fill, and
a hatch pattern. The hatch pattern has a hatch background color
assigned to it.
Hatches
and fills do not have to be bounded. In the following illustration, the
concrete hatches are bounded, while the earth hatches
are unbounded.
By default, bounded hatches are associative,
which means that the hatch object is associated with the hatch boundary
objects, and changes to the boundary objects are automatically applied
to the hatch.
To maintain associativity,
the boundary objects must continue to completely enclose the hatch.
The alignment and orientation
of a hatch pattern is determined by the current location and orientation
of the user coordinate system, in addition to controls in the user
interface.
Moving or rotating the
UCS is an alternate method for controlling hatch patterns.
NoteBy default, a preview
of the hatch displays as you move the cursor over enclosed areas.
To improve the response time in large drawings, turn off the hatch
preview feature with the HPQUICKPREVIEW system variable.
Alternatively, solid-filled areas can be created
using
To drag hatch patterns
into your drawing
NoteThis procedure describes
how to use DesignCenter to drag hatch patterns into your drawing.
You can also drag hatch patterns from a tool palette.
- On the DesignCenter toolbar, click Search.
- In the Search dialog box, do the following:
- From the Look For drop-down list, select
Hatch Pattern Files.
- From the In drop-down list, select the
drive where the program is installed.
- Confirm that Search Subfolders is selected.
- On the Hatch Pattern Files tab, in Search
for the Name, enter * (asterisk).
- Click Search Now.
The default hatch pattern
file is acad.pat or acadiso.pat. The search results
may display the same file in different locations.
NoteFor convenient access,
you can add the PAT file to Favorites by selecting the file and
clicking the Favorites button. A shortcut to the PAT file is displayed
in the Favorites folder in DesignCenter
folders list.
- In the search results, double-click the
filename to load the hatch patterns into the content area of DesignCenter.
- (Optional) Right-click a pattern to display
a shortcut menu with the following options:
- HATCH. Opens
the Hatch and Gradient dialog box.
- Copy. Stores
the hatch pattern on the Clipboard.
- Create Tool Palette. Creates
a new tool palette that contains the selected pattern.
- From the content area of DesignCenter,
drag a hatch pattern into an enclosed area in your drawing or onto
a tool palette.
NoteIf the hatch pattern
scale is too large or small, an error message is displayed. You
can adjust the scale for any hatch pattern by selecting it to display
the Hatch Editor tab. If the ribbon is closed, use the Properties
palette or
HATCHEDIT.
To hatch or fill areas
(ribbon turned on)
- On the Properties panel, select one of
the options from the Hatch Type drop-down list.
- On the Pattern panel, click a hatch pattern
or fill.
- Specify a point inside each area to be
hatched.
- On the ribbon, make any adjustments as
needed.
On the Properties panel,
you can change the hatch type and colors or modify the transparency
level, angle, or scale for the hatch.
- (Optional) Expand the Options panel,
and select one of the draw order options from the bottom drop-down
list.
You can change the draw
order of the hatch so that the hatch is displayed either behind
or in front of the hatch boundary, or behind or in front of all
other objects.
- Press Enter, or click Close on the ribbon
to apply the hatch and exit the command.
To hatch or fill areas
(ribbon turned off)
- In the Hatch and Gradient dialog box,
under Boundaries, click Add: Pick Points.
- Specify a point inside each area that
you want to hatch, and press Enter.
- In the Hatch and Gradient dialog box,
select a pattern or Solid from the Pattern list.
To see how the hatch
pattern will look, click the Preview button. Press Esc when you
finish previewing to return to the dialog box.
- In the Hatch and Gradient dialog box,
make adjustments, if necessary.
To access additional
options, click the More Options button at the bottom-right of the
dialog box.
- (Optional) From the Draw Order drop-down
list, choose one of the options.
You can change the draw
order of the hatch so that the hatch is displayed either behind
or in front of the hatch boundary, or behind or in front of all
other objects.
- Click OK to apply the hatch.
To hatch selected objects
(ribbon turned on)
- On the Boundaries panel, click Select.
- Select the objects that you want to hatch.
- Press Enter, or click Close on the ribbon
to apply the hatch and exit the command.
To hatch selected objects
(ribbon turned off)
- In the Hatch and Gradient dialog box,
under Boundaries, click Add: Select Objects.
- Select the objects that you want to hatch
and press Enter.
- Click OK to apply the hatch.
