So I am trying to make a system that clones the model in a random position. Here is my script:

local spawner = game.ReplicatedStorage.SpawnCage1
local cage = game.ServerStorage.Cage:Clone()
local cage1 = cage:GetChildren()

if spawner.Value == true then
	cage.Parent = workspace
	local position1 = Vector3.new(0,0,0)
	local position2 = Vector3.new(10,0,0)	
	local position3 = Vector3.new(20,0,0)
	local position4 = Vector3.new(30,0,0)
	local chosenPos = {position1,position2,position3,position4}
	cage.Position = math.random(1,#chosenPos)
elseif spawner.Value == false then
	cage.Parent = game.ServerStorage
end

Here is the error in output: 18:23:29.929 - Position is not a valid member of Model

If someone could help me out here that would be very nice. Thanks in advance.

Find the position of one of the parts, or average the positions of all of the parts.

Use Model:GetPrimaryPartCFrame().p Or Model.PrimaryPart.Position You will need to set a PrimaryPart though https://developer.roblox.com/en-us/api-reference/function/Model/GetPrimaryPartCFrame

Make all the parts a single union and set position of the union!
