boolean operation between tetrahedral meshes?

Hello,
I have two tetrahedral meshes: a complex object and a box. I would like to remove half of the complex object by subtracting the box. Is it possible to do that? In the example notebook it seems that only triangular meshes can be used as input...
Thank you!

Yes, we support only triangular meshes. For your case, I would extract the boundary of the two meshes and try with our algorithm
