how would i rotate the whole model using cframe.angles?

so when i’m using cframe.angles to rotate my model it only rotates the main part but not the whole model. i really don’t get it. i’m am confused can someone help me thank u

local rp = game.ReplicatedStorage
local dark = rp:WaitForChild("Right Hand")


game.Players.PlayerAdded:Connect(function(player)
	player.CharacterAdded:connect(function(character)
		character:WaitForChild("RightHand").Transparency = 0
		
		local ClonedRH = dark:Clone()
		ClonedRH.Parent = character
		
		ClonedRH:SetPrimaryPartCFrame(character:WaitForChild("RightHand").CFrame)
		local Weld = Instance.new("Weld")
		Weld.Part0 = ClonedRH.Main
		Weld.Part1 = character:WaitForChild("RightHand")
		Weld.C1 = CFrame.new(0,0,0) * CFrame.Angles(math.rad(30),math.rad(90),math.rad(20))
		Weld.Parent = character:WaitForChild("RightHand")
	end)
end)
