How to create a rotate feature with handles

im making a building game and i made rescale and moving handles with the Handles object, but im trying to make rotate, and its not as expected. im trying to replicate the studio rotate heres my current script:

local handles = script.Parent:WaitForChild("Rotation")
local cframeAtMouseDown
local lastStep = 0
local dragAxis
local dragSign

local faceToAxis = {
	[Enum.NormalId.Right]  = {axis = Vector3.new(0, 1, 0), sign = 1},  
	[Enum.NormalId.Left]   = {axis = Vector3.new(0, 1, 0), sign = -1},

	[Enum.NormalId.Top]    = {axis = Vector3.new(1, 0, 0), sign = 1},
	[Enum.NormalId.Bottom] = {axis = Vector3.new(1, 0, 0), sign = -1},

	[Enum.NormalId.Front]  = {axis = Vector3.new(0, 0, 1), sign = 1},  
	[Enum.NormalId.Back]   = {axis = Vector3.new(0, 0, 1), sign = -1},
}

handles.MouseButton1Down:Connect(function(face)
	local part = handles.Adornee
	if not part then return end

	cframeAtMouseDown = part.CFrame
	lastStep = 0

	local map = faceToAxis[face]
	if map then
		dragAxis = map.axis
		dragSign = map.sign
	end
end)

handles.MouseDrag:Connect(function(_, distance)
	local part = handles.Adornee
	if not part or not dragAxis then return end

	local step = math.floor(distance * dragSign * 2)
	if step == lastStep then return end
	lastStep = step

	local rotationAmount = step * math.rad(15)

	local worldAxis = cframeAtMouseDown:VectorToWorldSpace(dragAxis)
	local rotationCFrame = CFrame.fromAxisAngle(worldAxis, rotationAmount)
	local newCFrame = cframeAtMouseDown * rotationCFrame

	game.ReplicatedStorage.ChangeCFrame:FireServer(part, newCFrame)
	part.CFrame = newCFrame
end)

ye its ai, i dont know how to make rotate but ive made the other 2
