一、方法介绍
之前的博客介绍了如何在Pro中编辑倾斜摄影模型，参考博文：
在JS版本4.16版本之后，其实也支持在前端对发布的Scene Layer服务进行在线的编辑。通过 IntegratedMeshLayer 的modifications属性进行控制。
官网示例为交互式绘制GraphicLayer进行剪裁、掩膜及压平操作，具体可以参考官网DEMO示例：
二、根据发布的要素服务编辑模型
这里从一个Feature Layer要素服务读取面要素信息：
var polygonLayerUrl ='https://xxx.com/arcgisserver/rest/services/Hosted/polygon1/FeatureServer/0';
var queryTask = new QueryTask({
url: polygonLayerUrl,
});
然后通过 IntegratedMeshLayer属性修改modification属性，增加clip编辑效果：
queryTask.execute(query).then(function (results) {
const geometry = results.features[0].geometry;
console.log(geometry);
const modificaiton = new SceneModification({
geometry,
type: 'clip',
});
const modificaitons = new SceneModifications([modificaiton]);
debugger;
const sr1 = new SpatialReference({ wkid: 4326 });
const meshLayer = new IntegratedMeshLayer({
url: 'https://xxx.com/arcgisserver/rest/services/Hosted/Scenetest_WSL1/SceneServer',
spatialReference: sr1
});
meshLayer.modifications = modificaitons;
map.add(meshLayer);
});
具体效果：
