the first coordinate of the array is not used; must be initialized to (0.0, 0.0) for polygons, and to (-1.0, 0.0) for polylines,
Q1. I'm curious what the polygons here mean. At first I thought you meant a closed polyline. However, even if initialized to -1.0,0, the polyline was closed. So what does polygon mean?
The open polyline online works if you are creating a API_PolyLineType Element. Other element types with polygon information can only have closed polygons.
