Paste the following expression in a notebook and evaluate it.

FrontEndExecute[
  FrontEnd`HelpBrowserLookup[
    "AddOns",
    "Graphics`ContourPlot3D`"
  ]
]

This will summon the documentation for the standard package 
Graphics`ContourPlot3D`.  Loading the package into the kernel
will add a definition for a function named ContourPlot3D[].  
This function should do what you want.  The default behavior
is to generate the level surface f(x, y, z) = 0.
