[Chimera-users] periodic box visualization

Dear all, when a periodic system is visualized into Chimera (e.g., a periodic waterbox), is it possible to visualize explicitly the borders of the periodic box (defined for instance in the last line of coordinate/restart files in case of AMBER format structures)? Last, is it also possible to see the periodic images of the original box along X, Y & Z axes? How? I thank you in advance for the support and I look forward to receiving any feedback from you.
