I have a complex mesh with only vertices and edges that I want to solidify.

The problem is I just want to solidify edges (not any faces) to have some kind of fat wireframe model (i.e. just every edges being cylinders). Not a classic solidify.

How can I achieve that?

Here is my mesh: Solidify Edges

If you want to see a comparison of the results on my mesh: - Left: Beveling a Curve - Center: Wireframe Modifier with 0.5 Thickness and a Subsurf - Right: Skin Modifier with 0.5 Branch Smoothing and a Subsurf !Comparison I end up using the middle one (wireframe). It looks pretty organic without changing the initial shape of the mesh. – Binary Brain Apr 3 '14 at 17:04

You could use the Skin Modifier. After adding it to the object, it might appear fat and blobby, so to adjust the thickness you can Tab into Edit mode and use CtrlA to affect the thickness.

Another way is to just fill in the faces of your model and make use of the Wireframe modifier.

Beveling a Curve

Another way you can achieve your goal is to convert your Mesh composed of edges and vetices into a Curve. Then you could add a Bevel to the Curve and have your result. Here are the steps:

  1. Select your wireframe mesh
  2. Convert the mesh to a curve by either of these methods:

    • ALTC -> Curve from Mesh/Text
    • 3D Viewport Header -> Object -> Convert To -> Curve from Mesh/Text

    enter image description here

  3. Next, since you said you want to have every edge be a cylinder, you should Add a circle curve: SHIFTA -> Curve -> Circle

    enter image description here

  4. Now select your wireframe and in the Object Properties window, click on the Curve tab, scroll down to the Geometry section and set Bevel Object to the circle you added in step 3 -- this circle will then define the shape of the edges:

    enter image description here

  5. Now adjust the size of the circle curve so your mesh looks the way you want it to:

Thanks for the nice post. It may be useful once. But the problem is it's hard to rework on it afterward. – Binary Brain Apr 3 '14 at 16:55
Yes, also, if you zoom in on the corners, I noticed the cylinders of the edges don't join together like they do with the Skin Modifier or the Wireframe Modifier. – Thom Blair III Apr 3 '14 at 17:07
Actually, Binary, you can edit the mesh again, but I guess you do have to keep converting from curve to mesh in order to edit it easily. – Thom Blair III Apr 3 '14 at 18:04
@BinaryBrain Yes, now I see what you mean about hard to edit. Oh well. – Thom Blair III Apr 3 '14 at 18:08
Yes, modifiers are a lot more user-friendly for that. – Binary Brain Apr 3 '14 at 18:44
