How do I make the model as well as the PrimaryPart copy over in procedural generation?

So, I'm trying to make a procedural generation system similar to games like SCP: Secret Laboratory. The room templates are models that all have a PrimaryPart named "Floor" in them. However, only the Floor copies onto the map when generated, but not the model. Any ideas?

--Variables
local prefabs = game.ServerStorage.Prefabs
local rooms = 9
local width = 3
local length = 3
local x = 0
local y = 1
local z = 0
local rows = 0
local w = 0
local l = 0
local chance = 0
math.randomseed(tick())


function drawRoom(room, xp, yp, zp, location, num)
	if num == "" then
		local newRoom = prefabs[room]:Clone()
		newRoom.Parent = location
		newRoom.Floor.CFrame = CFrame.new(xp, yp, zp)
	else
		local newRoom = prefabs[room]:Clone()
		newRoom.Parent = location
		newRoom.Floor.CFrame = CFrame.new(xp, yp, zp)
	end
end

--Generation
for i = 1, width, 1 do
	for i = 1, length, 1 do
		wait()
		if w == width then
			w = 0
			rows = rows + 1
			x = x - 50
			z = z - 50
			print(l) --For testing purposes
			l = l + 1
		else
			chance = math.random(0, 3)
			if chance < 0.15 then
				drawRoom("EndRoom", x, y, z, workspace.World, chance)
			elseif chance < 1 and chance > 0.5 then
				drawRoom("Hall", x, y, z, workspace.World, chance)
			elseif chance > 1 then
				drawRoom("4Way", x, y, z, workspace.World, "")
			end
			w = w + 1
			z = z + 50
		end
	end
end

When moving a model with a PrimaryPart using regular CFrame only moves one part. When working with primary parts you need to use MoveTo or SetPrimaryPartCFrame. Most people will recommend using SetPrimaryPartCFrame because MoveTo collides with other parts.

Ex.

local x = 100
local y = 0
local z = 10

game.Workspace.Model.PrimaryPart = game.Workspace.Model.Part1

game.Workspace.Model:SetPrimaryPartCFrame(CFrame.new(x, y, z))
