Removing duplicate surfaces in box formation

Hi,

I am trying to get rid of all the interior face in the collection of boxes.  Here i show a small sample of them, 41 in total, but I am trying to do this on a much larger scale with hundreds of them. I am trying to identify the faces that are in the exact same place and cull both of them out.  I know that i could Boolean them all together but it would take forever.. I am looking for a much more efficient way.  I have looked at http://www.grasshopper3d.com/forum/topics/double-surfaces?page=1&am... and didn't find a solution.  

Separate boxes 

Here is the desired result with part of it pulled apart to show how there is no interior faces. 

Help would be much appreciated.  

Cheers

Have you tried to Boolean the boxes together? (Solid Union in Intersect-Tab)

Okay, I see.

How about this:

- explode all boxes

- calculate area/centroid of each face

- check if centroid has duplicates.

- cull faces with unique centroids...

-> BRep join remaining faces
