drawn. If the length is negative, the segment is pen-up, and it is not drawn.
The pattern starts at the origin point with the first segment and cycles through
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 on the Hatch contextual ribbon tab or in
the Hatch and Gradient 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

on page 75, 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:
