The [DashPatterns] settings define the eight dash pattern choices that appear in the Dashed Line Options dialog box. You can edit these settings to replace the standard choices with custom ones:
1=Dash, 8, 6
2=Hidden, 4
3=Longdash, 16, 10
4=Dot, 2, 4
5=Dash-Dot, 12, 6, 2, 6
6=Dash-Dot-Dot, 12, 6, 2, 6, 2, 6
7=Chain, 12, 6, 6, 6
8=Phantom, 20, 6, 6, 6, 6, 6
Each dash pattern contains a label that identifies the dash pattern in the Dashed Line Options dialog box and a repeating series of dash and gap segment lengths. Dashes and gaps are measured in points. The following illustration shows a dashed line and its segment description. The line is made up of a 12-point dash, a 6-point gap, a 6-point dash, and another 6-point gap. This pattern repeats to draw a dashed line of any length.
If a dash pattern setting contains an odd number of segment lengths, the last dash value is repeated for the final gap. For example, the following setting describes a dash pattern with 4-point dashes and 4-point gaps:
2=Hidden, 4
The dash pattern label cannot contain spaces or punctuation marks.
