I am using the Plot Frame Structure file from this link:
and utilizing it to plot lattice structures. I am trying to plot the structures with varying element thickness such that the element thickness can be visualized (say if there are total of 8 elements in a frame. 5 of them are 1mm thick, 2 of them are 1.5mm thick and last one is 2mm thick. When plotting the frame, I want to create the structure with elements thickness proportional to these thickness value). Additionally, it will be good to have these thicker elements (1.5mm, 2mm in the example) represented with different color as well than baseline thickness size (1mm in example). I do have node coordinate matrix, element connectivity matrix and a column vector of each element thickness which correspondes to the element connectivity matrix.
Any help is higly appreciated.Thanks

Hi Naresh,
You can modify the "plotStructure" function to plot the bars with varying thickness in the following way:
function plotStructure(nodes,bars,options)
% Plot nodes
if options.nodeOn == 1
% Plot bars
barX = [nodes(bars(:,1),1) nodes(bars(:,2),1)]';
barY = [nodes(bars(:,1),2) nodes(bars(:,2),2)]';
barZ = [nodes(bars(:,1),3) nodes(bars(:,2),3)]';
hold on
if ~isempty(options.barColor) && ~isempty(options.barWidth)
for b=1:size(bars,1)
hold off
% Other figure properties
gridMin = min(nodes);
gridMax = max(nodes);
xlim([gridMin(1) gridMax(1)])
ylim([gridMin(2) gridMax(2)])
zlim([gridMin(3) gridMax(3)])
pbaspect([1 1 gridMax(3)/gridMax(2)])
axis off
To use the modified plotStructure function, you need to add an additional property “options.barWidth” to the options structure. This property will be passed as an input argument to plotStructure, similar to how the color of each bar is passed through “options.barColor”. The “options.barWidth” property must be a column vector with the thickness value for each bar, in the same order as the bars in the bars input matrix.

Thank you Saffan for all your help. I had the options.barWidth property defined with a vector size of numOfBars x 1. I feel that the lineWidth variation is just not too large for me to be visibily distinguishable.
