How to use the PAT file

  1. Download the .PAT file, or copy the definition into your own pattern library file.
  2. AutoCAD: place the file in a support path, then choose Hatch, Pattern type Custom and pick the pattern name.
  3. Revit: Manage, Additional Settings, Fill Patterns, New, Custom, then import the .PAT file and set the import scale.
  4. Metric patterns assume millimetre drawing units; imperial patterns assume inches.
