Hi, I am trying to get MATLAB to output STL files of chaotic systems (Rossler, Lorenz, Chua). The graphs are made from iterating x, y, and z in a for loop. So I converted the vectors into a matrix using the vec2mat command. It gave me the STL files but the lines have no thickness. How can I resolve this problem? I tried adding space below the graph but it just makes a cylinder shape and doesn't thicken the lines. Please advise.
