Tube around mesh wireframe I need to generate a mesh where I can take the wireframe edges of the mesh and apply a shape to them so that the resulting mesh is long rods across those wireframe edges with the cross-section being of the shape I applied.

Below is similar to what I would like to do but instead of this, I would like it with a cylinder (or any shape if possible) 



I rather like gandalf3's answer above the one from Coburn as I need to export this effect to Unity, so I rather have a real mesh above a visualization in blender.

I include both as correct answers

Create a rounded wireframe?

How can I render an edge only mesh as solid lines?
Starting in edit mode you want to delete all faces from the mesh object X.



Then convert the mesh to a curve &#9095; AltC



Now that you have a curve object you can add any bevel shape you want to it by editing a new curve object to the shape and set it as the bevel object.



As you may notice in that screenshot, the curve from mesh object may need some cleanup. A mesh object can branch out many time from one vertex where a curve is one continuous line, this can leave "loose ends" in the generated curve.
