Converting a 3d area to a 2d area?

for i,v in pairs(workspace:GetChildren()) do
    if v.Name == "Intersection" or v.Name == "Road" then
        print("one")
        local y   = v.Size.X
        local z   = v.Size.Z
        local t   = v.Position.X
        local o   = v.Position.Z
        local gui = Instance.new("ImageLabel", script.Parent)
        gui.Parent = script.Parent.Frame
        gui.Size  = UDim2.new(0,y,0,z)
        gui.Position = UDim2.new(0,t + 350,0,o + 350)
        gui.BackgroundColor3 = Color3.new(1,1,1)
        gui.ZIndex = 4
    end
end

this is my attempt for turning a map (road map) into an in-game GUI of that map, but it really falls short on rotations and stuff like that.
