Json

{"curveRings":[[[267.04948078483386,105.79047954003055],{"a":[[267.04948078483386,105.79047954003055],[267.04948078483386,58.983530044912435],0,0,1.5707963267948966,46.806949495118111,0.3298589584470854]}]		]

要素导出的Json

{"displayFieldName": "","fieldAliases": {"字符串字段": "字符串字段","OBJECTID": "OBJECTID","Shape_Length": "Shape_Length","Shape_Area": "Shape_Area"},"geometryType": "esriGeometryPolygon","spatialReference": {"wkid": 102100,"latestWkid": 3857},"fields": [{"name": "字符串字段","type": "esriFieldTypeString","alias": "字符串字段","length": 255},{"name": "OBJECTID","type": "esriFieldTypeOID","alias": "OBJECTID"},{"name": "Shape_Length","type": "esriFieldTypeDouble","alias": "Shape_Length"},{"name": "Shape_Area","type": "esriFieldTypeDouble","alias": "Shape_Area"}],"features": [{"attributes": {"字符串字段": null,"OBJECTID": 1,"Shape_Length": 1636200.7474000081,"Shape_Area": 162473325914.95126},"geometry": {"rings": [[[12784999.967099998,4750538.0075000003],[13263682.9727,4750538.0075000003],[13263682.9727,4411120.6393999979],[12784999.967099998,4411120.6393999979],[12784999.967099998,4750538.0075000003]]]}}]
}

由此看出几何导出的Json只是要素导出Json的其中一部分。所以工具箱中的Json转要素是不适用于几何的Json。
