I had insomnia the other night, and made this tutorial. It teaches you to make a flying saucer in 3D using blender.
Blender is free.
I hope self subs are ok here?
This is a good tutorial for beginners or intermediate blender users, suggested to me by a member of our local home education forum.
Up until I tried this tutorial, I had steered intentionally clear of NURBS objects.
You can always use alt-c to convert a NURBS to a mesh.
Not a video tutorial this time, but that is ok.
