HATCHING IN AUTOCAD
-
In order to hatch in AutoCAD you need to draw objects forming a closed area. Beginning with AutoCAD 2005, it became acceptable to hatch an area with a small opening.
-
AutoCAD comes with a good number of generic pre-defined hatch patterns saved in a file called acad.pat. You can also buy other hatch patterns from third-parties, which can be found on the Internet.
-
A Hatch, like any other object, should be placed in a separate layer.
-
There are two methods to hatch in AutoCAD, the old method (Hatch command) and the new method (Tool Palette).

Under the Hatch tab, select the Type pop-up list and you will see the following choices:
User Defined
-
The most simple hatch pattern has parallel lines. Once this option is selected the following parameters will be valid:
-
Swatch: to display a preview of the hatch.
-
Angle: the angle of the parallel lines.
-
Spacing: the distance between two parallel lines.
-
Double: which means, in both ways.
-
-
The following is a User defined hatch, using Angle = 45 and Double hatch:
Predefined
-
There are a handful of hatch patterns available for use.
