<p>P.S. I hope it's also very clear that without posting your model, this kind of response, specific to you, is impossible. In most cases, almost any response without a model is just a waste of time.</p>

<p>I also used the tree viewer on the flattened box output... shows that grasshopper is looking at all of the pieces in a grid format like a matrix where the sequential count for a column carries over row by row and then continues to the next column.</p>

<p>Does this help? Before and after 'SUnion' images, the first pair (without 'Flip') has no effect - do you understand why? The second pair uses 'Flip Matrix'; see the difference? Hint: 'SUnion' (like many GH components) works only on lists and treats each branch as a separate list.</p>

<p>You're right... I do need a better understanding of the data tree... </p>
<p></p>
<p>Flattening it did work, Thank you!</p>
<p></p>
<p>In follow up, I went back again used the parameter viewer to get a better sense of what's going on (not all that helpful here), it did show 7 branches, which go to 1 when flattened...</p>
<p></p>
<p>My confusion now is why did it work for one group and not the other group before either of them were flattened?</p>

<p>the two unions in the bottom right near the large text box are what's giving me problems</p>
