How would I convert CFrame to Vector3?

So, I'm making a DBZ game, and I need to move a part along a ray or part. In order to draw this beam/part I need 2 Vector3 values, I've got the Handle of the tool and the Mouse.Hit (Which is CFrame)

Is there anyway to convert a CFrame to Vector3?

Scripts:

Local Script in a Tool

local Tool = script.Parent
local Mouse = game.Players.LocalPlayer:GetMouse()
local Player = game.Players.LocalPlayer
local Event = game.ReplicatedStorage.ToolEvent

script.Parent.Activated:connect(function()
    Event:FireServer('Ki Blast', Mouse.Hit, Tool.Handle)
end)

ServerController Script :

local Atk = require(script.Parent.Attacks.AttackGenerator)
local Attacks = require(script.Parent.Attacks.Attacks)
local Morphs = require(script.Parent.Transformations.Transformations)
local PService = require(script.Parent.PlayerService)
local Event = game.ReplicatedStorage.ToolEvent

Event.OnServerEvent:connect(function(Player, AtkName, Target, Handle)
    if AtkName == 'Ki Blast' then
        Atk.KiBlastStart(Player, Target, Handle)
        PService.Values[Player.Name].Charging = true
    elseif AtkName == 'Ki Beam' then

    elseif AtkName == 'Ki Beam Release' then

    end
end)

Attack Module Script

local Atk = {}
local AtkValues = require(script.Parent.Attacks)
local PService = require(script.Parent.Parent.PlayerService)
local PValues = PService.Values
local Parts = game.ReplicatedStorage.Parts
local Sounds = game.ReplicatedStorage.Sounds
local DS = game:GetService('Debris')

local DrawBeam = function(beamstart, beamend, clr, fadedelay, templatePart)
    local dis = (beamstart - beamend).magnitude
    local laser=templatePart:Clone()
    laser.BrickColor = clr
    laser.Size = Vector3.new(.1, .1, dis + .2)
    laser.CFrame = CFrame.new((beamend+beamstart)/2, beamstart) * CFrame.new(0, 0, - dis/2)
    laser.Parent = workspace
end

Atk.KiBlastStart = function(Player, Target, Handle)
    local Counter = 0
    local Orb = SphereSynthesizer(Player, Target, Handle, 0.35, 'Bright bluish green', Vector3.new(0,0,0), true, Enum.Material.Neon)
    repeat
        wait()
        Counter = Counter + 1
        Orb.Mesh.Scale = Vector3.new(Counter/2,Counter/2,Counter/2)
    until Counter > 10
    Counter = 0
    Atk.KiBlastLaunch(Player, Target, Handle, Counter, Orb)
    DS:AddItem(Orb, AtkValues.Ki['Ki Blast'].Range)
end

Atk.KiBlastLaunch = function(Player, Target, Handle, Size, Orb)
    DrawBeam(Handle.Position,Target, BrickColor.new('Really red'), 5, Parts.Cube)
    local Play = Sounds.KiBlast:Clone()
    Play.Parent = Orb
    Play:Play()
    Orb.Parent = workspace
    Orb.Anchored = false
    Orb.Velocity = Vector3.new(0,100,0)
    Orb.CanCollide = true
    wait(3)
    for i=5,20,0.5 do wait()
        Orb.Mesh.Scale = Vector3.new(i*5,i*5,i*5)
        Orb.Transparency = Orb.Transparency + 0.025
    end
end
