About hatch patterns with multiple lines

  1. Open an existing PAT file or create a new file in a text editor that saves in ASCII format (for example, Notepad on Windows® or TextEdit on Mac OS®).

    Note: If you are creating a new PAT file, the PAT file and pattern must have the same name.

  2. Create a header line that begins with an asterisk and includes a pattern name that is no more than 31 characters in length.

    For example, *ANGLE

  3. Optionally, include a description for the hatch pattern by adding a comma and descriptive text after the pattern name.

    For example, *ANGLE, Angle steel

  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

    For example, 0, 0,0, 0,.275, .2,-.075

  5. Create a second line including all the parameters in the previous step.

    For example, 90, 0,0, 0,.275, .2,-.075

  6. Optionally, create additional lines to complete the multiple-line hatch pattern.

  7. 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.
