Polyline Command

Polyline( <List of Points> ): Creates an open polygonal chain (i.e. a connected series of segments) having the initial vertex in the first point of the list, and the final vertex in the last point of the list.

The polygonal chain length is displayed in the Algebra View.

Polyline( <Point>, …, <Point> ): Creates an open polygonal chain (i.e. a connected series of segments) having the initial vertex in the first entered point, and the final vertex in the last entered point.

The polygonal chain length is displayed in the Algebra View.
It is also possible to create a discontinuous polygonal:

Polyline((1, 3), (4, 3), (?,?), (6, 2), (4, -2), (2, -2)) yields the value 9.47 in Algebra View, and the corresponding polygonal in Graphics View.
