At the top of the map has a little hand and a little pen. The little hand drags the map and the canister makes the drawing. To draw, you need to select the pinch, click on the map point where you want to start the neighborhood drawing and then click again at another point on the map to form a line. You are creating multiple lines until you close the drawing. You do not need to leave the mouse down to drag the line, just click once at a point and then click to click each point on the map you want to leave marked.
