To draw polyline:
start point> 0,0
next point> 10,0
next point> 10,10
next point> 0,10
next point> close (or click in "close" button)
With this command sequence are created a CLOSED "squared" polyliline

and:
start point> 0,0
next point> 10,0
next point> 10,10
next point> 0,10
next point>  0,0
With this command sequence are created a OPEN "squared" polyliline

The result with both methods is the same visually, but the first creates a closed polyline and the second an open polyline with the coordinates of the first point equal to the last point.


In this image left polyline are closed, and right are open, with "Edit->Modify Properties" you can check if polyline are open or closed (and change the status)
