Melt
This Node's functionality reflects that of the Melt modeling function in the Mesh menu and can be used to combine selected elements in an N-Gon. Note that points on the geometry can end up being deleted if these are not needed after melting.
After selecting several polygons on a sphere, these can be reduced to an N-Gon using the Meld Node and flattened at the top pole, as in this example.
