[SOLVED]How to make both parts in a model move together using "mouse.Hit.p"?

So, i'm trying to make a building system. I want models with multiple parts to move together .

But my outcome ends up with one part in the correct position(although slightly clipped into the ground).

SCREENSHOTS

My Model

My model hierarchy

My tool hierarchy

What happens

SCRIPT

-- May add a remove event for server side soon.


local test = game:GetService("ReplicatedStorage").Buildings.Test -- My Building
local tool = script.Parent -- Get the Tools
local db = false -- Debounce
local mouse = game:GetService("Players").LocalPlayer:GetMouse()

tool.Activated:Connect(function()
	if db == false then
		db = true
		local building = test:Clone() -- Clone it
		building.Parent = workspace
		
		local position = mouse.Hit.p -- Calculate the position
		
		building.PrimaryPart.Position = position -- Using PrimaryPart, because i thought it would work with multiple parts
		
		wait(1)
		
		db = false
		
	end
end)

(fyi im not a good scripter at this kind of stuff, ok?)

Alright, multiple problems. your first issue is that to move an entire model, you have to cframe it instead of setting a position. AKA instead of building.PrimaryPart.Position = position do building.PrimaryPart.CFrame = CFrame.New(position). Second, to unclip it from the ground you need to add half the height of the model, so just add change it to local position = mouse.Hit.p+Vector3.new(0,building:GetExtentsSize.y/2,0). Also this one is too big for me to solve, but if this is a localscript then it wont actually place, it'll only look like it did to that one player.
