Element: linestyle.offset
Element: linestyle.offsetnumeric
The offset of the line from its defined center line. A positive value will produce an offset to the right, and a negative value of 1 to the left, looking from line start to finish. By defining various offsets, parallel composite line patterns can be created. The plane in which the offset is effective is determined by linestyle.offset_mode.
If this element is not defined, a value of 0 is assumed.
