Why is this mesh operation failing?

Grasshopper

I am trying to perform the difference between the original terrain mesh and the cut volume, but it always returns the same mesh.

Can you upload the file? I don’t know the reason, but it doesn’t work for me:

but: it was drawn with Rh8 and I see now that it fails with Rh7.
[edit]
btw a ‘far from origin’ problem, if you bake and move both meshes zu 0,0,0 it works in Rh7 too.

That’s not the answer I wanted to receive, but it solved the problem. Thanks!
