代码：

export function showDraw(isFlyTo) {removeLayer()graphicLayer = new mars3d.layer.GeoJsonLayer({data: {type: "FeatureCollection",features: [{type: "Feature",geometry: {type: "Point",coordinates: [121.453893, 29.888391],},properties: {gid: "1",code: "1718850737365",type: 'circleP',style: {radius: 1693.63}},id: "fid--45368680_1902ac1ce0f_-7fde",},],},symbol: {styleOptions: {color: "#FF0000",},},flyTo: true});map.addLayer(graphicLayer);
}

效果：

报错：

Cesium.js:15236 An error occurred while rendering.  Rendering has stopped.
DeveloperError: normalized result is not a number
Error

处理办法：

设置下 merge为true即可，

正确代码：

export function showDraw(isFlyTo) {removeLayer()graphicLayer = new mars3d.layer.GeoJsonLayer({data: {type: "FeatureCollection",features: [{type: "Feature",geometry: {type: "Point",coordinates: [121.453893, 29.888391],},properties: {gid: "1",code: "1718850737365",type: 'circleP',style: {radius: 1693.63}},id: "fid--45368680_1902ac1ce0f_-7fde",},],},symbol: {merge: true,styleOptions: {color: "#FF0000",},},flyTo: true});map.addLayer(graphicLayer);
}

正常效果：

原因：

1.内置的style与symbol配置冲突，需要合并并覆盖json中已有的style
