I tried...
the problem is that I have an STL file with inside a cube and a sphere.

I read STL file and I add it to a viewport here is the code:

                Dim readmodel3d As New Model3DGroup

                Dim assimpWpfImporter As New AssimpWpfImporter
                readmodel3d.Children.Add(assimpWpfImporter.ReadModel3D(mfile))
                Dim modelarray = New ModelVisual3D
                modelarray.Content = readmodel3d
                myview.Children.Add(modelarray)

I added an handler but when i click on the sphere and apply a trasformation the transformation is applied on shere and on cube.

So i can hint the single object.

Where I,m wrong?
