the segments in circular fashion. A dash length of 0 draws a dot. You can
specify up to six dash lengths per pattern line.
The hatch pattern ANSI33, shown in the Boundary Hatch and Fill dialog box,
looks like this:
and is defined as follows:
*ANSI33, ANSI Bronze, Brass, Copper
45, .176776695,0, 0,.25, .125,-.0625
For example, to modify a pattern for 45-degree lines to draw dashed lines with
a dash length of 0.5 units and a space between dashes of 0.5 units, the line
definition would be
*DASH45, Dashed lines at 45 degrees
45, 0,0, 0,.5, .5,-.5
This is the same as the 45-degree pattern shown in Overview of Hatch Pattern
Definitions on page 27, but with a dash specification added to the end. The
pen-down length is 0.5 units, and the pen-up length is 0.5, meeting the stated
objectives. If you wanted to draw a 0.5-unit dash, a 0.25-unit space, a dot, and
a 0.25-unit space before the next dash, the definition would be
*DDOT45,Dash-dot-dash pattern: 45 degrees
45, 0,0, 0,.5, .5,-.25, 0,-.25
The following example shows the effect of delta-x specifications on
dashed-line families. First, consider the following definition:
*GOSTAK
0, 0,0, 0,.5, .5,-.5
This draws a family of lines separated by 0.5, with each line broken equally
into dashes and spaces. Because delta-x is zero, the dashes in each family
member line up. An area hatched with this pattern would look like this:
