Snapping moving object

Help and Feedback Scripting Support

Ok so originally I was using this to snap my part to a grid

local PosX
local PosY
local PosZ

local GridSize = 2

function Snap(mouse, model)
	PosX = math.floor(mouse.Hit.X / GridSize + 0.5) * GridSize
	PosY = model.PrimaryPart.Position.Y
	PosZ = math.floor(mouse.Hit.Z / GridSize + 0.5) * GridSize
	
	return PosX, PosY, PosZ
end

Model:SetPrimaryPartCFrame(CFrame.new(PosX, PosY, PosZ) * CFrame.Angles(0, math.rad(Rotation), 0))

Now this code worked, but problem with it was that I couldn’t place the model on walls or it would be go in between walls.

So now I want to use this code as it works on placing the object on the walls, etc. Code from this post Placement System For Wall Objects - #9 by Imaginze

local UnitRay  = Camera:ScreenPointToRay(Mouse.X, Mouse.Y, 1)	
local NewRay = Ray.new(UnitRay.Origin, UnitRay.Direction * 1000)
local Hit, Pos, Normal = workspace:FindPartOnRay(NewRay, Model)
Model:SetPrimaryPartCFrame(CFrame.new(Pos, Pos + Normal * 15) * CFrame.Angles(-math.rad(90), math.rad(Rotation), 0) * CFrame.new(0, Model.PrimaryPart.Size.Y / 2, 0))

Problem with this code however is that it doesn’t snap to a grid

Can anyone help with incorporate my original code with this new code?
