Suggestion for 3D application

[math7]

Hello, It would be possible to implement in the new 3D application the functionality of being able to make a "cut in x" or "cut in and" as it is in the HP 50g? It would be useful to be able to give an idea in graphs a little complex at first glance in which it costs to distinguish well the details or the "form" of the graph through one of the axes.
