Change a part's CFrame while following the mouse?

I'm trying to make it so wherever your mouse goes, the part follows it. So far it's good, but the problem is that the mesh seems to be positioned the wrong way. Since the mesh inside the part is a ring, part of the ring is going through the ground. Here is the chunk of code:

while true do
    wait()
    nukeTarget.CFrame = CFrame.new(character.Humanoid.TargetPoint.X , 1, character.Humanoid.TargetPoint.Z)
end

Is there any way to make it so the ring looks flat?
