How to make a grid placement system?

Hello everyone! I’m trying to make a grid placement system where a player clicks a button to place an object and rotate, delete it, other factors too etc. I also have a currency system and I want to make it so when the player puts down the furniture, it takes their money away. I’ve followed countless tutorials but most of them are all outdated :,) . How could I achieve this?

Im not going to make the whole thing for you, but I can provide a function that rounds the objects position to a grid, just to get you started?

local function snapToGrid(position)
	local snappedX = math.floor(position.X / 2 + 0.5) * 2
	local snappedY = math.floor(position.Y / 2 + 0.5) * 2
	local snappedZ = math.floor(position.Z / 2 + 0.5) * 2
	
	return Vector3.new(snappedX, snappedY, snappedZ)
end

Then from here you have to get the Players Mouse Position in 3D space. I have also made a function for that(best way imo):

local UserInputService = game:GetService("UserInputService")
local Camera = workspace.CurrentCamera

function returnMousePosIn3DSpace() : Vector3
	local MouseLocation = UserInputService:GetMouseLocation()
	local MousePositionin3D = Camera:ScreenPointToRay(MouseLocation.X, MouseLocation.Y)
	
	return MousePositionin3D.Direction
end

Here are 2 basic starting blocks for your building system, now you have to customise and make your own version with furniture, cash, and removing.
