4

I want to plot blocks (transportation pallets). Each block has 0.8m width, 1.2m depth, and 2.15m high, and they are placed horizontally (only one block height) grouped 2x2, 3x3, 4x4, 5x5, 6x6, 7x7 blocks.

I have been testing the two solutions of "Need help creating a 3D cube from a 2D set of nodes in TikZ " but I do not know how to adapt the code to my problem.

For example, I would like to change the cuboids dimensions of this example:

That has 2 layers of blocks when I want to plot only 1 layer, and the xyz dimensions of the cubes are the same, and I would like to change the x, y and the z dimension of the cuboids.

I have also tested the second solution, and also I was not able to get the result I am looking.

If possible, I would like also to place a label with the total dimension of each group of blocks at the x, y, and z dimensions. I do not know if it is possible that the text of the labels can be aligned with the same side angles of the figure. For example, in the case of a 2x2 group of blocks will be in the x dimension 1.6m, the y dimension 2.15 m (only one level of blocks) and the z dimension 2.4m.

EDIT

Using marmot's solution below, and

scalex=0.8,%
scaley=2.0,%
scalez=0.5,%

I would like to place text with the dimensions of each side of the group. For example:

I guess in the code you are using it was not foreseen to have only one cube in a given direction. To remedy this, I replaced

\foreach \x in {\steppingx,\secondx,...,\dimx}

by

 \ifnum\dimx=1
 \def\lstx{\dimx}
 \else
 \def\lstx{\steppingx,\secondx,...,\dimx}
 \fi
 \foreach \x in \lstx

and similar for other directions. Other than that, the dimensions in the various directions are set by keys like scalex, which I set to 2 in the MWE

UPDATE: I added some keys for the egde labels. Note, however, that they may not look good if you use (very) different angles. Nor did I use siunitx to typeset the distances (because I do not want to flood this answer with not directly related packages). If you want a solution in which the labels look good for all possible angles, please ask a separate question.

  • Thank you. I have edited the question with a plot using your solution, and with the labels I would like to place – user1993416 Dec 28 '18 at 10:47
  • I have tested slight changes in the angles, and the figure and labels look fine to me. I will post a new question if I see a problem playing later with your code. – user1993416 Dec 29 '18 at 9:24
