// Shows total command count and first command information in cells.
let worksheet = Api.GetActiveSheet();
let fill = Api.CreateSolidFill(Api.RGB(100, 150, 200));
let stroke = Api.CreateStroke(18000, Api.CreateSolidFill(Api.RGB(50, 75, 100)));
let shape = worksheet.AddShape("star5", 60 * 36000, 60 * 36000, fill, stroke, 3, 0, 2, 0);
let geometry = shape.GetGeometry();
let path = geometry.GetPath(0);
