Answer 1

scenecontrol里是根本没显示，还是一片绿呢？

如果是后者，可能是电脑显卡性能的限制。

我的问题是我想在工作空间打开三维模型，但是每次打开之后是超图地球的模型

.NET我没有用过，不过我没有看到你的scenecontrol和workspace绑定。

谢谢，确实出现了这个问题

Answer 2

您好！首先，scenecontrol和workspace需绑定，代码如下：m_sceneControl.Scene.Workspace = m_workspace;

其次，无需FlyToModel（），删除即可 。因为您打开的是工作空间里已经保存的场景，无需让它飞行到该场景中，打开直接就是您保存这个场景时的位置。

您的代码简化后如下：
