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
