I have just gotten Blender 3D, and was wondering how to create a wireframe. Could someone please guide me on how to do this?
This depends on which Render Engine you are using.
For more realistic Results you should select
Set up your scene (Camera, Lamp, Object), select your Object and choose
In Cycles this is a bit more complicated, but here is a template: BlendSwap
Here are some really great tutorials you can look into if you are having trouble: Blender Cookie
Since blender 2.70, there is a wireframe modifier which you can use to easily create wireframe models.
