I have created a 3D image of a subsurface reservoir using the 3D surface
chart. I would like to add additional images to the same chart, so that the
chart will illustrate overlying subsurface reservoirs.

I have attempted to do this using Chart - Add data
but the resulting chart will display my original data ... the new data is
displayed as a vertical wall.

Is it possible to display more than one 3D surface image on a single chart
in Excel.

Thanks
