根据报错信息看,问题很明确了,这种类型的数据集坐标系不支持,你看一下你的数据集是什么坐标系,只有地理坐标系或者投影坐标系的数据能够添加到三维球面场景,你这个数据集是新建的,你可以设置一下dataset的坐标系属性,

Dataset..::.PrjCoordSys 属性

再给你说一下,你看一下你添加到数据集里面的点的坐标是多少,如果x是正常的+-180范围内,Y在+-90范围内,那就是地理坐标,你设置一个地理坐标系就可以了,如果是很大的值,就是投影坐标,设置一个投影坐标系
设置了地理坐标系 但是球上不显示呢
下面这段代码 能否麻烦您修改成能够在球上显示呢

这么设置

添加进去后,定位当当前图层

Scene.EnsureVisible()上面的图层
可以了  十分感谢
客气啦,解决了可以点击一下采纳结题
