I have a "Working" Dart script that is supposed to create a special mesh server-side positioned from a part in the local tool. The only thing that I could get to work was to list the Dart's CFrame as a CFrame.new() and that spawns the dart at the default location (0,0,0)

--functions
	local function Shoot(player,mouse,tool)
		print("Shot Initiated") 
		local target = CFrame.new(mouse.Hit.p)
		local spawnposition = CFrame.new(tool.Handle.Postion,target)
		  local Dart = Instance.new('Part') do
	    -- Set up the dart part
	        Dart.Name = 'Dart'
	        Dart.FormFactor = Enum.FormFactor.Custom --NOTE: This must be done before                                                     changing Size
	        Dart.Size = dartsize
	        Dart.CanCollide = false
	    -- Add the mesh
	        local mesh = Instance.new('SpecialMesh', Dart)
	        mesh.MeshId = dartmesh
	            mesh.Scale = meshscale
	    -- Add a force   to counteract gravity
	        local bodyForce = Instance.new('BodyForce', Dart)
	        bodyForce.Name = 'Antigravity'
	        bodyForce.force = Vector3.new(0, Dart:GetMass() * Gravity, 0)
	        print("MeshCreated")
		-- Create a clone of dart and set its color
	        local dartClone = Dart:Clone()
	        --game.Debris:AddItem(dartClone, 30)
	        dartClone.BrickColor = BrickColor.new(33, 60, 122)
	        -- Position the dart clone and launch!
		dartClone.CFrame = CFrame.new() --NOTE: This must be done before assigning Parent
		dartClone.Velocity = dartClone.CFrame.lookVector * dartspeed --NOTE: This should be done before assigning Parent
		dartClone.Parent = game.Workspace		
	    end
	end
Click.OnServerEvent:Connect(Shoot)
