Question

From the answer to this question, is it possible to make a lower cube position void, to create this drawing

Yes. I added an optional parameter which indicates how many boxes are to be skipped. So 2/1 means two boxes but skip the first one.

Let me mention that in the above the old syntax is, of course, still functional. So if you drop the /1 you will get the original result. But with this method you do not have to draw two partitions. — , Jan 20 '19 at 07:06
I tried your suggestion, but unfortunately it did not work. Would you please give me the whole code. — Hany, Jan 20 '19 at 07:25
I am sorry your answer was not displayed when I posted my comment. I followed your answer and it works fine. Thank you. — Hany, Jan 20 '19 at 07:28
Thank you very much. Both your answer and AndréC`s work fine. I am confused about which answer to mark!!! — Hany, Jan 20 '19 at 07:43

In this case, it is sufficient to build layer by layer (floor by floor) from the lowest to the highest.

To do this, I modified the loop by adding an optional argument that is set to 0 by default. This allows you to keep the old syntax for previous graphics.

This optional argument is simply added to the z counter in the loop:

\addtocounter{z}{#1}

By default, this argument is 0 and builds the partition like the old code, i.e. on the ground floor.

When this argument is equal to 1, it builds a partition one floor above.
when it is equal to 2, it builds two floors above, etc.

It is always possible to build several layers (or floors) at the same time as in the old code.

\newcommand\planepartition[2][0]{
 \setcounter{x}{-1}
  \foreach \a in {#2} {
        \addtocounter{x}{1}
        \setcounter{y}{-1}
            \foreach \b in \a {
            \addtocounter{y}{1}
            \setcounter{z}{-1}
            \addtocounter{z}{#1} %partition of the desired floor (layer)
            \ifnum \b>0
            \foreach \c in {1,...,\b} {
                \addtocounter{z}{1}
                \cube{\value{x}}{\value{y}}{\value{z}}
      }\fi
    }
  }
}

Thank you very much for your answer. Both your code and marmot`s work fine. — Hany, Jan 20 '19 at 07:39
Thank you, my way of doing things allows you to place several holes on the same column. — AndréC, Jan 20 '19 at 07:40
