Each Hatching Style defines two style/colour pairs, either style may 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 may 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. for further information about hatch-patterns see Hatching Rules.
The HSTYL attributes, with their defaults, are as follows:

By default, when a length of implied tubing or a DUCT or STRT (ducting straight) element is cut and the resulting face is circular or rectangular, Draft will generate a typical sectioned symbol rather than just apply the hatch pattern to the face:

The PIPESYM attribute of Hatching Styles allows this functionality to be suppressed and replaced by normal hatching.
