Edit: Smoothing problem solved, one more modelling question in my third post of this thread.
I am relatively new to blender and now I have a problem modelling an ammunition ring for toy guns. The model itself is basically finished (not sure if there would be a better way to model it, but I guess so… :o)
My problem is that when I smooth it now, it happens to have weird looking lines on the model (see picture). I have already removed doubles and also recalculated the normals. The problem is still there.
Also when I draw the normals, they seem to point in different directions quite randomly (see picture).
Does anyone know what might be wrong here? Do I have to remodel the mesh?
Here is also the .blend-file.
Thanks in advance for your help!
