Using CFrame to move an object to a position?

Use TweenService! Tweening is used for interpolating almost any numeric property of certain objects. In your case, I'm assuming, a part.

So here's how it goes;

local TweenService = game:GetService("TweenService") --gets tween service

local part = workspace.Part --gets the part (change it to your own part's address)

local tweenInfo = TweenInfo.new( --how we want our tween to play
    1, --how fast the tween is (in seconds)
    Enum.EasingStyle.Linear, --easing style
    Enum.EasingDirection.Out, --easing direction
    0, --no. of times the tween will repeat
    false, --will the tween reverse upon finishing?
    0 --how long the delay is (in seconds)
)

local goal = { --goal for our part's property, in this case, the position
    Position = Vector3.new(69,42,0) --our goal position for our part
}

local tween = TweenService:Create(part, tweenInfo, goal) --now creates the tween

tween:Play() --finally, plays it
