Is it possible to use ContainerUIElement3D in conjunction with SortingVisual3D? I would like sorted visuals that have the power of the ContainerUIElement3D class.

Hi Simon! I have not tried this, but I guess it should be possible. Let us know if there is a bug. And remember that the SortingVisual3D is only a 'basic' work-around for the transparency problem...

Thanks for replying. I was asking if it is possible as I can't get it to work. If I add a ModelUIElement3D object as a child of a ContainerUIElement3D object, and add the ContainerUIElement3D object as a child of a SortingVisual3D object, I find that the mouse events are not fired.
e.g. (geometry code excluded)
var element = new ModelUIElement3D(); element.Model = geometry; element.MouseDown += this.ContainerElementMouseDown; var containerUI = new ContainerUIElement3D(); containerUI.Children.Add(element); var uiTransparentElements = new SortingVisual3D(); uiTransparentElements.Children.Add(containerUI); viewport.Children.Add(uiTransparentElements);
It is not too big a deal since I could use VisualTreeHelper.HitTest instead of ContainerUIElement3D, but I was wondering if I was missing something simple.

ok, could changing the base class of HelixToolkit.Wpf.RenderingModelVisual help? Try replace ModelVisual3D by ContainerUIElement3D (I am guessing - no time to test right now).

I did start to try that but unfortunately abandoned as didn't resolve all the build errors. I will use HitTest workaround for now. Is it possible to add to future enhancement list?

ContainerUIElement3D is a noniheritable class...

Then try to add a ContainerUIElement3D to the ModelVisual3D.
