ModelUIElment3D
UIElment3D is .NET3.5 new category, replacing the ModelVisual3D. There are two ModelVisual3D derived classes ModelUIElment3D and ContainerUIElment3D. ModelUIElment3D with ModelVisual3D biggest difference is that, without the use of HItTest to detect a specific 3D object model mouse clicks. Instead, a standard 2D name of the event MouseLeftButtonDown.
