DOUBLE SURFACES

If I have 2 identical surfaces sharing the same space, how can i remove one and keep the other. Without a manual way like list item or cull item, I mean to remove duplicate surfaces, same as remove duplicate points or lines components in kangaroo. Thanks

I also just thought, what if lets say i have only some overlapping surfaces and some not, and i only want to get rid of overlaps, then I need to somehow say "if area is repeated then remove 1" here i get lucky because they all overlap so I can simply sort them and remove everyother which I have done. hmnnnn.

Wouldn't all cell faces overlap except for edge-bordering cell faces? That looks to be the case in the image above.

yes with voronoi, but in other cases I mean, like this for instance. http://www.grasshopper3d.com/photo/orange-peel-1?context=user. only there the closed breps meet would there be an overlap.

also can you look at my definition i just sent, I cannot figure out im removing the exterior shell with in or out component, for somereason when I lower the voronoi point number to say 20 points, the in out doesnt get rid of the correct surfaces.

So I did this for the case when you have just surfaces to work with... I didn´t suppose that I would have 2 different surfaces with the same area in my model... This simple solution helps with area comparison when there´s not a pattern in duplicated surfaces... watch out for 1st and last member, I figured it´s not a big deal to be left having to check 2 members...
