Hello @salah It’s unclear what you are asking. Can you give more context around what you’re trying to do? In general terms: 1. A polygon is a closed polyline, where the last point is identical to the first point. Perhaps if you remove the last point of the polygon, it will behave more like a polyline. 2. a shape is somewhat dependent upon the ShapeType that you specify for the layer to which it is added, (although I’ve accidentally put polylines into a polygon layer, which appear to be interpreted as ‘open’ polygons, and things can get confusing).
