Nothing complicated, just access methods to read the values.

A line is defined as:

(dotLen, distance) * numDot, distance (dashLen, distance) * numDash

Means: numDot dots with dotLen, followed by numDash dashes with DashLen, 
all seperated by distance-gaps.

Of course. Open LO, draw a line, choose '3 Dashes 3 Dots' as LineStyle.
