[SOLVED BY ME] How would I randomize the position of a model?

#Introduction

When creating a tree, I implemented a system where the tree will randomize its position every time it is chopped down. However, the tree is a model and I tried using :GetChildren() to solve it, but it didn't work.

#Script

Here's my script:

local player = game.Players.PlayerAdded:Wait()
local character = player.Character or player.CharacterAdded:Wait()
while not character.Parent do
	character.AncestryChanged:Wait()
end
local Humanoid = character:WaitForChild('Humanoid')
local HRP = character:WaitForChild('HumanoidRootPart')

local mouse = player:GetMouse()

local Anim = Instance.new("Animation",script.Parent)
Anim.Name = "ChopAnim"
Anim.AnimationId = 'rbxassetid://3027147369'
local Animation = Humanoid:LoadAnimation(Anim)
local Part = script.Parent

local currentChops = script.Parent.CurrentChops
local maxChops = script.Parent.RequiredChops

game.ReplicatedStorage.PressedE.OnServerEvent:Connect(function()
	if (HRP.Position - Part.Position).magnitude < 6 then
		if player.PlayerGui.Job.Value == "Lumberjack" then
			print("is job")
			Humanoid.WalkSpeed = 0
			Humanoid.JumpPower = 0
			Animation:Play()
			script.Parent.ChopSFX:Play()
			for i = 0,10,1 do
				currentChops.Value = i
				wait(script.Parent.ChopSFX.TimeLength)
			end
			currentChops.Value = 0
			script.Parent.BillboardGui.Enabled = false
			script.Parent.ProgressOfInter.Enabled = false
			Humanoid.WalkSpeed = 16
			Humanoid.JumpPower = 50
			Animation:Stop()
			script.Parent.ChopSFX:Stop()
			script.Parent.FallTree:Play()
			for i = 0,1,.1 do
				script.Parent.Transparency = i
				script.Parent.Parent.Branch.Transparency = i
				script.Parent.Parent.Branch1.Transparency = i
				wait()
			end
			script.Parent.Name = "Cooldown"
			local LogClone = game.ReplicatedStorage.Log:Clone()
			LogClone.Parent = player:WaitForChild('Backpack')
			game.ReplicatedStorage.TreeCut:FireClient(player)
			script.Parent.Position = Vector3.new(math.random(-100,100),script.Parent.Position.Y,math.random(-100,100));
			wait(script.Parent.FallTree.TimeLength)
			for i = 1,0,-.1 do
				script.Parent.Transparency = i
				script.Parent.Parent.Branch.Transparency = i
				script.Parent.Parent.Branch1.Transparency = i
				wait()
			end
			script.Parent.Name = "Tree"
			script.Parent.BillboardGui.Enabled = true
			script.Parent.ProgressOfInter.Enabled = true
		else
			game.ReplicatedStorage.NotJob:FireClient(player)
			print("does not have job of lumberjack")
		end
	end
end)

#Conclusion

Sorry if it's a little hard to read...

I have no idea how I would make the branches go randomize WITH the tree, not randomize independently. I tried using WeldConstraints, but it didn't work.

Any help please? I've tried all the methods I know.

EDIT: Apparently, you can actually use Unions to help with this type of situation. It solved my question, so yay!
