Making a hollow cylinder - Blender 2.80 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?
Really dependent of what you want to do once the base shape is done. Above two possibilities, but both may be wrong if the afterpart (if there is) needs a different geometry.

You can 'screw' + 'boolean', starting from a single edge:



Also you can 'spin' twice + 'bridge edge loops':



Spin is more manually done: make a spin for the inner part with x steps (starting from a single vertex). Make a second spin for the outer with also x steps (starting from another single vertex). Select all and in the menu in edit mode 'Edge>Bridge edge loops'.

The resulting geometry is different as the second, more manual approach, keeps quads. Depends on what you want to do after that.
