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) ⎇ AltC -> select Mesh From Curve/Meta/Surf/Text
3) select Edit Mode
4) A then ⎈ 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:
