You can hide density that is farther than a cutoff from selected atoms, and then if you actually want to delete the hidden part, you can save a new density map with values in the hidden area set to zero.
Hiding the zone: In Volume Viewer, go to the Features menu, choose Zone to show the zone controls in the dialog. Select the atoms of interest, then click the Zone button. The cutoff radius can be edited directly or controlled with a slider.
Saving a new density map with values outside the zone set to zero: After applying the zone, use "File... Save map as" in the Volume Viewer menu.
I hope this helps,
