orthogonal projection of 3D nodes onto a 2D plane

I need to project 3D nodes (nodes) onto a 2D plane that I got from the code in FEX.

load xyz

fobjPlane=planarFit(xyz);
for i=1:2
    subplot(1,2,i);
    [hL,hD]=plot(fobjPlane); %Visualize the fit
end
legend([hL,hD],'Plane fit', 'XYZ samples', 'Location','northoutside','FontSize',15);
subplot(1,2,1)
view([-69.5 -24.6])
subplot(1,2,2)
view([9.6 -35.2])

So I need to always get nodes in space however that lie on that plan.

You should post questions about a FEX file on the submission's FEX Discussion forum, since only its author is likely to have the answer. In any case, the answer is to use the fobjplane objects' project2D() method, as demonstrated at the FEX page in the Advanced Topics section of the Examples tab,

fobjplane.project2D(xyz)
