The document discusses hatching in AutoCAD, including recent enhancements to the HPLAYER system variable in AutoCAD 2017. It allows the user to create a new drawing layer and set it as the hatch layer simultaneously. The document also provides tips for hatching, such as creating user-defined hatch patterns by modifying the pattern scale, properly defining the enclosed hatch area using polylines or boundary/region commands, and starting the HATCH command on a separate hatch layer.

Layer Tips & Tricks

Among many things new in AutoCAD 2017 is Hatch
Layer Enhancements.
l
AutoCAD 2017 improvements to the HPLAYER
system variable helps you to create a new drawing
layer and set it as the hatch layer in a single go. The
HPLAYER system variable was introduced in
AutoCAD 2011, so one can specify an existing layer
on which one can create new hatches and fills in spite
of the current layer.

Hatching is an artistic technique which is used to
create tonal or shading effects by drawing , scribing
or painting closely spaced parallel lines. It is mainly
important in linear media, such as drawing, and
many forms of printmaking, such as etching ,
engraving and woodcut.

4. How it works ?
l
The quantity, thickness and spacing of the
lines will affect the brightness of the overall
image, and emphasize forms creating an
illusion of volume. Hatching lines should
always follow the form. By increasing
thickness ,quantity and closeness, a darker
area results.
l
Hatching can sometimes be annoying, so we
have collected a few hatching tips together for
you.

6. Create user­defined hatch patterns
l
When you select a hatch pattern and apply it,
many times it doesn’t look the way you want it
to. So an easy way to deal with this problem is
to create a user­defined hatch pattern. It just
lets you specify the angle of the pattern and its
scale. Changing the scale is an easy way to
correct a hatch pattern whose spacing are too
closer or wider.

8. Start the HATCH command
l
Before you start hatching, you might want to create a
separate layer for the hatch and make it current. When
you start the HATCH command (Home tab> Draw panel>
Hatch), the Hatch Creation tab appears. Choose the
pattern you want from the Pattern panel.
l
Define the enclosed area properly
l
Sometimes, Auto CAD doesn’t hatch the correct area.
Here are some hints for defining the enclosed area:
l
Instead of lines, Franck Wallez advises drawing with
polylines. One reason is that they make specifying an
enclosed area easier. If the enclosed area is complex, use
the BOUNDARY or REGION commands to create a
closed area.
