Grasshopper - Parametric Truss Tutorial

David Fano is yet again kind enough to share his Grasshopper expertise in a new video tutorial.

In this Grasshopper video, he will create a parametric truss system by generating and manipulating components and instantiating them onto a lofted geometry.

I have been trying the Parametric Truss tutorial from the Grasshopper tutorial page and have run into an issue when I get to the point where the filleted polyline triangles need to display as holes instead of the outside triangles. At the stage where the sample file displays this way, my model shows both triangles as solid. Even though in the previous step, where the inner triangles are solid, the inner triangles in my model are also solid.
I think that the sample file uses an earlier version of Grasshopper, so I'm not sure if this is the reason. I have spent some time reviewing my steps and always come to the same conclusion. I know it is difficult for you without seeing my file, however can you offer a solution as to why this is happening off hand?

Any advice is greatly appreciated.
