How to fill the surface of a "wireframe"-sphere in Blender I have half a sphere together with a full sphere as separate objects in a blender file. I load them from a X3D file I generate externally. I get them as something, which seems to be something like a wire-frame to me (maybe different what Blender calls wire-frame-objects). Instead of this wire-frame I want a closed surface – one for the sphere and one for the half sphere.



The problem is that I am a total beginner in Blender. What I have tried so far is the following:

1) select one of the objects (let's say the full sphere, see first image)

2) &#9095; AltC -> select Mesh From Curve/Meta/Surf/Text

3) select Edit Mode

4) A then &#9096; CtrlF

My hope was that Blender only fills the faces orthogonal to the normals of the sphere. Unfortunately it does not work like I hoped. Could someone help me a bit. I am a total beginner to blender and mostly do not know how to access the options, if someone could explain it for an absolute beginner, this would help me a lot.

I attached a blend-file:
You probably have curves. So when converted to mesh, they are disconnected rings or arcs but this is not visible as vertices overlap.

In edit mode: 


select all
remove doubled vertices (you find that in the toolshelf on the left using T to make it appear, or press W to bring up the menu to select it from)
then once all is selected hit F


I confirm this hypothesis after a test on your file.



Concerning the half sphere, same principle but you'll have to remove the unwanted face after that:


Switch to face selection mode CtrlTab, then choose 'face'
Select it RMB
Delete it X then 'only face'
