Cull Duplicated Surfaces

I created a small definition to be able to remove duplicated surfaces.
Hope it works for everyone as it works for me :)

What's the watch object? doesn't seem to load?

Does this rely on the centrepoint being the unique identifier for the geometry?

Sorry, now Im ataching an example.
If you for example have some boxes as the one on the .3dm file, just make sure to extract all the faces and flatten all of them in a single list.

Yes, rely only on the centerpoint.
Hope it works for you

Right, gotcha.

That's neat little way of doing it when you know that touching faces are the same shape (and centre point)

thanks for that

Hi Natalia, I found a problem with your script, if making a 3x3x3 array of boxes. your scripts fails to remove the surfaces of the very centre box. Do you have a solution for this?
