local plr = game.Players.LocalPlayer
local mouse = plr:GetMouse()

local GridSize = 2

local Part = workspace.Part

local function snap()
	local PosX = math.floor(mouse.Hit.X / GridSize + 0.5) * GridSize
	local PosY = math.floor(mouse.Hit.Y / GridSize + 0.5) * GridSize
	local PosZ = math.floor(mouse.Hit.Z / GridSize + 0.5) * GridSize
	
	return PosX, PosY, PosZ
end

game:GetService("RunService").RenderStepped:Connect(function()
	mouse.TargetFilter = Part
	local posx, posy, posz = snap()
	local unitRay = mouse.UnitRay
	
	Part.CFrame = Part.CFrame:Lerp(CFrame.new(posx, posy, posz) * CFrame.new(0, Part.Size.Y / 2, 0), 0.4)
end)

The parts intersect. I need help finding a way to prevent this.
