creat 2D slices in MS

Just see a good image in one paper, using Materials Studio Volume Visualization tool to creat 2D slices parallele to the x,y,z-axes to show the volume occupied by water aggregates as a red spots.

Does anyone have a idea how to do that? Thanks very much!

I have tried the Volume Visualization tool, however all the task for it are black, I can not use the tool. I don't know why.
