Hi there,

I generated a shape using contourf in MATLAB and I wish to put it into FEA analysis to make it a CAD model based on the same profile (green area) with certain thicknees. Can anyone please help or provide some guidance? Many thanks.

% Below code should work for my code
C = contourf(fnx, flipud(fny), xg-ls, [0 0]);  % plot the data
X = C(:,1); % X coordinate data
Y = C(:,2); % Y coordinate data
Z = zeros(size(C,1),1);
FID = dxf_open('polylines3.dxf'); 
dxf_polyline(FID,X,Y,Z); 
dxf_close(FID);
