I was wondering if there is a convenient way of increasing the hit test area of a MultiPolyLineVisual3D?  The only solution i can think of is to duplicate the MultiPolyLineVisual3D and make this duplicated line transparent with a bigger LineThickness and use this for handling mouse over/click events and then perform actions on the associated visible line.  I'm using the EventManager3D for event handling. The problem with this is doubles the number of lines I have on screen which adds overhead.
