DRAW Reference Manual
Graphical Representation : Automatic Hatching : Hatching Styles
Each Hatching Style defines two style/colour pairs, either style can be set OFF. The Fill Style and Fill Colour (FSTYLE and FCOLOUR) attributes define the hatch pattern to be applied to the selected faces. The Outline Style and Outline Colour (OLSTYLE and OLCOLOUR) attributes define the lines that can be drawn around the edges of the faces. For example, it is possible to emphasise an area by drawing a thick line around it without actually hatching it. Refer to Hatching Rules for further information.
