Placing Script Not Placing Properly?

Before We begin here are some things you should know the Heirarchy

Problem: The following script does everything it is saposed to do, but when the part if following the mouse, and when I finally place it, it does not place right It looks like this , although i want to be placed like this , Also if i leave the mouse still while I'm in placing mode, the item will get closer and closer

Script

local cam = game.Workspace.CurrentCamera
local Item = game.ReplicatedStorage.Building.Walls.WoodenWall
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local enabled = script.Parent.Enabled
local amount = script.Parent.Amount
local Placing = false


script.Parent.MouseButton1Down:connect(function()
	
if enabled.Value == true then
	enabled.Value = false
elseif enabled.Value == false then	
	enabled.Value = true
	end
if Placing == true then
	local Item2 = cam:WaitForChild('WoodenWall')
	local Torso = game.Workspace:WaitForChild(player.Name).Torso
	local mag = (Item2.Position - Torso.Position).magnitude
	print(mag)
	if mag <= 40 then
	Item2:WaitForChild('bob'):remove()
	Item2.Parent = game.Workspace
	Item2.CFrame = mouse.Hit + Vector3.new(0, 50, 0)
	Item2.CanCollide = true
	Placing = false
	enabled.Value = false
	amount.Value = amount.Value - 1
end
end
end)

script.Parent.MouseButton2Down:connect(function()
	if enabled.Value == true and amount.Value >= 1 then
		
		local Item2 = Item:Clone()
		Item2.Parent = cam
		local selectionBox = Instance.new("SelectionBox",Item2) --We set its parent, but not where it's going to overlay
		selectionBox.Adornee = Item2 
		selectionBox.Name = 'bob'
		selectionBox.Color = BrickColor.new("Lime green")
		Placing = true
		
		
		
		
		
		repeat
			wait(.1)
		Item2.CFrame = mouse.Hit
		until enabled.Value == false or amount.Value < 1		
	end
	
end)

The reason the part gets closer when you leave it still is because it's pointing at the object and it is moving to the mouse's position. You'd need to set the mouse's target filter to the model you're wanting to place
