BLock moving stop location?

So i try to make a part that spawns when i click on a gui and then it rotates and moves. Everything is working but i wonder how i can do so it stops move and rotate at a specific position like when it have reached another parts position because its very hard to find the right place with the "For Loop"

My Code looks like this for the moment btw this script is inside PlayerGui.ScreenGui.TextButton

function onClicked()
    x = Instance.new("Part", game.Workspace)
    x.Size = Vector3.new(10,10,10)
    x.Position = Vector3.new(5,5,5)
    x.BrickColor = BrickColor.new("Bright blue")
    x.Transparency = "0.1"
    x.Anchored = true
    x.TopSurface = "Smooth"
    x.BottomSurface = "Smooth"
    for rm = 1,380 do
        x.CFrame = x.CFrame *CFrame.Angles(0.1,0.1,0.1)
        x.Position = x.Position +Vector3.new(0,0,0.1)
        wait()
        end     
x:remove()
wait()
end

script.Parent.MouseButton1Click:connect(onClicked)

the most important to part to look at i think would be.

for rm = 1,380 do
        x.CFrame = x.CFrame *CFrame.Angles(0.1,0.1,0.1)
        x.Position = x.Position +Vector3.new(0,0,0.1)
        wait()
        end

Btw Sorry for my grammar and English
