Hello, I was looking for help on converting my existing placeable system to work with models. Currently it only works with parts but I have been trying for the past couple of days to figure out a some what simple way to incorporate models. Here is the code, I added a few labels to make reading easier digest:

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local PlaceStructure = ReplicatedStorage:WaitForChild("PlaceStructure")
local Structures = ReplicatedStorage:WaitForChild("Structures")

local UIS = game:GetService("UserInputService")
local RunService = game:GetService("RunService")

local player = game.Players.LocalPlayer
local StructureFrame = script.Parent.StructureFrame 
local char = player.Character or player.Character:Wait()
local HumanoidrootPart = char:WaitForChild("HumanoidRootPart")

local mouse = player:GetMouse()

local yBuildOffset = 5
local maxPlacingDistance = 50
local rKeyIsPressed = false
local placingStructure = false

for _, structureButton in pairs(StructureFrame:GetChildren()) do 
	if structureButton:IsA("TextButton") then
		structureButton.MouseButton1Up:Connect(function()

			StructureFrame.Visible = false

			local yOrientation = 0
			local goodToPlace = false
			local placedStructure 

			if placingStructure == false then 
				placingStructure = true
------------------------------------------------------Problem Area----------------------------------------------------

				local clientStructure = Structures:FindFirstChild(structureButton.Name):Clone() -- Grabs the part that is matched to the name of text button in GUI
				--------------------Fancy Looks so you can see what your placing--------------------
				clientStructure.BrickColor = BrickColor.new ("Forest green")
				clientStructure.Material = "Neon"
				clientStructure.CanCollide = false
				clientStructure.Parent = game.Workspace
				------------------------------------------------------------------------------------
				local startingCFrame = CFrame.new(0, -2, -15)
				clientStructure.CFrame = HumanoidrootPart.CFrame:ToWorldSpace(startingCFrame)

				RunService.RenderStepped:Connect(function()
					local mouseRay = mouse.UnitRay
					local castRay = Ray.new(mouseRay.Origin, mouseRay.Direction * 1000)
					local ignoreList = {clientStructure, char}
					local hit, position = workspace:FindPartOnRayWithIgnoreList(castRay, ignoreList)

					if hit and (hit:IsA("Terrain") or hit.Name:lower() == "terrain") and (HumanoidrootPart.Position - clientStructure.Position) .Magnitude < maxPlacingDistance then --decides if plcemnt area is good or bad
						goodToPlace = true
						clientStructure.BrickColor = BrickColor.new("Forest green") --Keeps color green if in valid placment area
					else
						goodToPlace = false
						clientStructure.BrickColor = BrickColor.new("Crimson") --Changes color red if not in valid placment area
					end

					local newAnglesCframe = CFrame.Angles(0, math.rad(yOrientation), 0)
					local newCFrame = CFrame.new(position.X, position.Y + yBuildOffset, position.Z)
					clientStructure.CFrame = newCFrame * newAnglesCframe
				end)

				UIS.InputBegan:Connect(function(input)
					if input.KeyCode == Enum.KeyCode.R then
						rKeyIsPressed = true

						local rotationSpeed = 5
						while rKeyIsPressed do 
							wait()
							if placingStructure == true then 
								yOrientation = yOrientation +rotationSpeed

							end
						end
					end
				end)

				UIS.InputEnded:Connect(function(input)
					if input.KeyCode == Enum.KeyCode.R then 
						rKeyIsPressed = false
					end
				end)
				---------------Accessing and placing object (object placement handled elsewhere)--------------
				UIS.InputBegan:Connect(function(input)
					if input.UserInputType == Enum.UserInputType.MouseButton1 then
						if placingStructure == true then 
							if goodToPlace == true then
								local SructureCFrame = clientStructure.CFrame
								placedStructure = PlaceStructure:InvokeServer(clientStructure.Name, SructureCFrame)

								if placedStructure == true then
									placingStructure = false
									clientStructure:Destroy()
									StructureFrame.Visible = true
---------------------------------------------------------------------------------------------------------------------------------------------------------									
								end
							end
						end
					end
				end)
			end
		end)
	end
end
