use 2nd order interpolation (3-node line elements)?

In recent nightly builds you can use the "Normal raise" option (in
Options->View->Offset)

I can't use 3-node line elements in my solver (Code Aster)...by all
means, it shouldn't be necessary to use 2nd order beam elements,
because 1st elements are exact in static linear analysis. Any other
suggestions?
<br>
</blockquote>
<br>
Maybe I don't understand your question. If you have a single line
element with vector nodal values (1 vector associated with each
extremity), we cannot represent anything else that the linear
interpolation over the element...

Ok, I'll try to explain my goal better. We know that when a distributed
load acts the correct moment of a beam is parabolic; I'd like to see a
parabola when I use "Normal raise" option to represent the moment.<br>
Is it possible with gmsh?<br>
You suggested to use 3-node line elements: I try to write a simple file
.msh but probably I'm wrong in something...<br>
