A beam section for each would give something like this:
** Element sets for materials and FEM element type (solid, shell, beam, fluid)
** written by write_element_sets_material_and_femelement_type function
and would go on until all beams are here...
Things I think would be necessary:
Instead of bundling them into one entry when no line is selected in the beam cross-section icon, we need to generate them individually.
On all individual beam we should define the correct (x.,y.,z.)
Missing now is the algorithm to pick a element direction node P1 (X1,Y1,Z1)->P2(X2,Y2,Z2) that forms a element E1 and will require the correct normal point. I am considering a fixed n1 so we get to play with n2 adapting to the element in hand.
