Overview of Hatch Pattern Definitions

1 Open the acad.pat or acadiso.pat file in a text editor that saves in ASCII

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-y of any value
Hatch Patterns with Dashed Lines
To define dashed-line patterns, you append dash-length items to the end of
the line definition item.
To define dashed-line patterns, you append dash-length items to the end of
the line definition item. Each dash-length item specifies the length of a
segment making up the line. If the length is positive, a pen-down segment is
drawn. If the length is negative, the segment is pen-up, and it is not drawn.
The pattern starts at the origin point with the first segment and cycles through
the segments in circular fashion. A dash length of 0 draws a dot. You can
specify up to six dash lengths per pattern line.
The hatch pattern ANSI33, looks like this:
and is defined as follows:
