How could i delete a Model using a script?

local ClickDetector = workspace.Part.ClickDetector

function buildapole ()
    local lowpart = Instance.new("Part") -- Getting the lowest part
    lowpart.Parent = game.Workspace
    lowpart.Position = Vector3.new(4 , 0.5 , 0)
    lowpart.Size = Vector3.new(6 , 1 , 6)
    lowpart.Anchored = true
    lowpart.Material = Enum.Material.Wood
    lowpart.BrickColor = BrickColor.new("Brown")

    local midpart = Instance.new("Part") -- Getting the Cylinder
    midpart.Parent = game.Workspace
    midpart.Position = Vector3.new(4, 5.5, 0)
    midpart.Size = Vector3.new(12, 7, 3)
    midpart.Anchored = true
    midpart.Material = Enum.Material.Wood
    midpart.BrickColor = BrickColor.new("Brown")
    midpart.Shape = Enum.PartType.Cylinder
    midpart.Orientation = Vector3.new(0 , 0 , 90) -- Rotate 90 Degrees


    local ballpart = Instance.new("Part") -- Getting the Sphere
    ballpart.Parent = game.Workspace
    ballpart.Anchored = true
    ballpart.Position = Vector3.new(4, 13.5, 0)
    ballpart.Shape = Enum.PartType.Ball
    ballpart.Size = Vector3.new(7, 7, 7)
    ballpart.Material = Enum.Material.Neon
    ballpart.Color = Color3.new(1, 0.980392, 0.384314)

    local Polemodel = Instance.new("Model")
    Polemodel.Parent = game.Workspace
    Polemodel.Name = "PoleModel"
    lowpart.Parent = game.Workspace.PoleModel
    midpart.Parent = game.Workspace.PoleModel
    ballpart.Parent = game.Workspace.PoleModel


end
ClickDetector.MouseClick:connect(buildapole)

i created a light Pole and Grouped them in a Model

i tried to use script on the DevForum to delete the Model Group through Click Detector on a Part

Can somebody give me a script that could destroy it on Click with a Part?

Thank Everyone
