How can I combine multiple surf plots into 1 stl file?

Let's say I have a rectangle box composed of 3 surf plots, the yellow top, a bottom face(hidden) and the four sides in purple. Is there a way to combine the 3 plots together into 1 .stl file?

Thanks.

Have you been able to solve this problem? I would also be interested in an answer.

Hi,

• You can use ‘surf2stl’ to convert individual surf plots to .stl file. The ‘surf2stl’ function can be found here: - https://www.mathworks.com/matlabcentral/fileexchange/4512-surf2stl
• After converting, you can use 'Meshmixer' or any other similar software to combine the .stl files into a single .stl file.

You don't need surf2stl(). You already have surf2patch(), so just use it to get F,V data from your gridded data. Once you have F,V data, combine them and write it to an STL file. It's not necessary to use external software to combine anything.
