Hatch Patterns with Dashed Lines
To create a hatch pattern with dashed lines
1 Open the acad.pat or acadiso.pat file in a text editor that saves in ASCII
format.
2 Create a header line that includes an asterisk and a pattern name. The
name of the hatch pattern is limited to 31 characters.
3 (Optional) To include a description in the header line, follow the pattern
name with a comma and description text.
4 Create a descriptor line that includes
 An angle at which the line is drawn
 An X,Y origin point
 A delta-x of any value if you want to offset alternating lines in the line
family
 A delta-y of any value
 A value for a dash length
 A value for a dot length
 An optional second value for a different dash length
 An optional second value for a different dot length
Hatch Patterns with Multiple Lines
Complex hatch patterns can have an origin that passes through offsets from
the origin and can have multiple members in the line family.
Not all hatch patterns use origin points of 0,0. Complex hatch patterns can
have an origin that passes through offsets from the origin and can have
multiple members in the line family. In composing more complex patterns,
you need to carefully specify the starting point, offsets, and dash pattern of
each line family to form the hatch pattern correctly.
The hatch pattern AR-B816 looks like this:
and is defined as follows with multiple lines describing the pattern:
