Make sure your Breps are grafted and your Curve is flattened. Then get the list length of the intersection results, and test whether or not it is equal to 0. Use the boolean result of the Equals component as the pattern by which to dispatch your original list of Breps.

Very clever use of lists to obtain a geometric result!

only you would add the function to join breps selecting only the tetrahedra. the oppositemay select any triangle.
