Hi Mir4ea, there's nothing really set up like that currently, since mostly MoI is focused on precision construction and just using an arbitrary angled 3D view direction for something like an extrusion vector is sort of fundamentally imprecise...

There are a couple of scripts you can set on a shortcut key that will align the cplane to the current view direction, if that helps. Check out here:

Do you have a link that shows how the Zbrush clipping mask works?
