题
我挣扎得到的PropertyPath工作 - 我得到了在窗口的资源,我试图通过故事板影响转型 - 也是在窗口资源...
赫雷什我使用的属性路径...
(Viewport2DVisual3D.Transform).(Transform3DGroup)[0].(RotateTransform3D).(RotateTransform3D.Rotation).(AxisAngleRotation3D.Angle)
编辑:感谢Anurags建议,我已经有了一个有点进一步... (Viewport2DVisual3D.Transform)。(Transform3DGroup.Children)[0]。(RotateTransform3D.Rotation)。(AxisAngleRotation3D.Angle)
,但现在它与“旋转属性不指向一个DependencyProperty”
的错误任何人都可以请让我回到正轨?
下面有完整的代码...

解决方案
首先代替DoubleAnimation是,使用三维关键帧动画。
和使用纠正你StoryBoard.TargetProperty的语法(Transform3DGroup.Children)而不是
