Code does not plot my values above a certain z coordinate

Hi, i'm very new to matlab and have become stuck with plotting a 3d rectangle above a certain patch level.

The aim of my code is to create a 3D spacial model depending on what the user inputs. This includes them being able to specify the number, size (width and length) and heights of certain floors, followed by the number, size (width and length), height and where they wish to plot spaces using coordinates.

The spaces seem to just become 2D after the second floor has been plotted.

I hope someone understands this

Thank you for any help in advance :)

You've got way too much code here to expect others to wade through in order to get to where there may be a problem and it's not possible to see what might be wrong simply by a visual inspection --

As a general suggestion, it would seem likely the plotting cases could be resolved into a single function with input values which could then be tested independently for proper function. This would also have the marked benefit of reducing the amount of code by a sizable amount.

Failing in the above, the alternate suggestion would be to create a much shorter example case that illustrates the problem -- for this, pick a set of inputs you know that causes the problem to appear and supply those a constants and remove all the user interface stuff and loops and post that code so somebody has a chance to see/reproduce the problem.

Failing in that, set a breakpoint and use the debugger to see where your logic fails in generating what you expect.

I will see what i can do. Thank You!

Are you sure the code in each block is different? It looks the same, though I didn't scrutinize it. If they're all the same then no matter what answer is you'll get the same patches.

Hi Ethan,

I understand that you are trying to create a 3D spatial model in MATLAB based on user input, where the user can specify various parameters such as the number of floors, the dimensions of each floor, and the dimensions and locations of certain spaces within those floors. However, you are encountering an issue where, after plotting the second floor, the spaces intended to be 3D are only appearing as 2D.

On analyzing the provided code, it seems like all of the "patch" subroutines are identical for "if-else" statements.

The id-else code snippet can be summarized as follows:

if answer == 1
    % series of patch commands with 'red' color
elseif answer == 2
    % identical series of patch commands with 'red' color
elseif answer == 3
    % identical series of patch commands with 'red' color
% ... and so on for answer == 4 and answer == 5
end

Therefore, MATLAB will produce identical patches irrespective of the value of answer variable.

Consider changing the arguments to the "patch" utility to get different outputs.

Hope this helps.
