Polyline
Similar to polygon, but using the absolute value of the winding number instead of odd-even filling.
Syntax
polyline { \(Px [,]\)\{3,n\} range { \(<low,high>\)\{1,m\} } OBJECT_MODIFIERS }
n coplanars points Px
<low,high> specification of interval for winding numberWinding number
Only the absolute number is considered (the notions of clockwise & anti-clockwise vary with the orientation of the system).
