Please check [this thread](https://discourse.slicer.org/t/vmtk-surface-clipping-contribution/30456/7) throughout.

@DavidM wrote a [module](https://github.com/dmolony3/ClipVessel) that does just that.

Alternatively, other manual methods are suggested in the [thread](https://discourse.slicer.org/t/vmtk-surface-clipping-contribution/30456) pointed to.
