I am trying to recreate the C64 logo in 3D, which roughly looks like this: C=
My thought was to create a cylinder the size of the C, then create a second cylinder the size of the inside of the C, lay them ontop of eachother and cut the smaller cylinder out of the large cylinder, then draw a square to cut off the right side of the new shape to create the 3D C.
But I'm struggling with the first part, making a hollow cylinder.
I've tried the knife project tool but it does not cut a hole into the cylinder. I've also tried to set a modifier but it says it cannot apply the modifier because it is set to disabled.
I'm using Blender 2.80.
What is a good way to approach this?
