Create a header line that includes an asterisk and a pattern name. The name of the hatch pattern is limited to 31 characters.
Note: If you are creating a new PAT file, the PAT file and pattern must have the same name.
(Optional) Include a description in the header line, follow the pattern name with a comma and description text.
For example, ``*ANSI33, ANSI Bronze, Brass, Copper`
45, 0,0, 0,.25
45, .176776695,0, 0,.25, .125,-.0625
Add a blank line after the last descriptor line.
Note: If the blank line is missing, the hatch pattern won’t be recognized by the program.
