Why the following code does not add an arc to a schematic lib?:
    api('createShape', {
        "shapeType": "arc",
        "stroke": "#8D2323",
        "stroke-width": "1",
        "cx": 400,
        "cy": 300,
        "rx": 20,
        "ry": 20,
        "start-angle": 0.1,
        "end-angle": 2.7
   });
Thanks!
