Truss with frames and rigid plates

hi,

I have a 3d truss with a few plates in the frame. how do I insert a plane into the truss frame?

It is my understanding that you would like to insert a plane into the 3D truss you have.

Use the patch function and insert the plane in the truss frame. It can be done in the following way:

% For the sake of explanation, I have created a truss with rigid plates and inserted the plane therein

% Define the coordinates of the truss nodes
nodes = [0, 0, 0; 0, 0, 5; 0, 5, 0; 0, 5, 5; 5, 0, 0; 5, 0, 5; 5, 5, 0; 5, 5, 5];

% Define the connectivity matrix for the truss elements
connectivity = [1, 2; 1, 4; 1, 5; 2, 3; 2, 6; 3, 4; 3, 7; 4, 8; 5, 6; 5, 8; 6, 7; 7, 8];

% Define the coordinates of the rigid plates
plateVertices = [0, 0, 0; 0, 5, 0; 5, 5, 0; 5, 0, 0];

% Define the coordinates of the plane vertices
planeVertices = [0, 0, 1; 0, 2.5, 1; 5, 2.5, 1; 5, 0, 1]; % Can also replace with the indices of the desired truss nodes for the plane

% Plot the truss
figure;
hold on;

% Plot the truss nodes
scatter3(nodes(:, 1), nodes(:, 2), nodes(:, 3), 'filled');

% Plot the truss elements
for i = 1:size(connectivity, 1)
startNode = nodes(connectivity(i, 1), :);
    endNode = nodes(connectivity(i, 2), :);
    line([startNode(1), endNode(1)], [startNode(2), endNode(2)], [startNode(3), endNode(3)]);
end

% Plot the rigid plates
patch('Vertices', plateVertices, 'Faces', [1, 2, 3, 4], 'FaceAlpha', 0.5, 'FaceColor', 'blue');

% Plot the plane
patch('Vertices', planeVertices, 'Faces', [1, 2, 3, 4], 'FaceAlpha', 0.5, 'FaceColor', 'red');

% Set axis labels and limits
xlabel('X');
ylabel('Y');
zlabel('Z');
axis equal;
grid on;

% Adjust the view angle
view(3);
