Draggable Clone for Models?

I'm trying to get one of my models to be cloned, turn a little transparent and then move with the mouse when I click on a button. I've made it so it is cloned and moves with the mouse but It breaks apart and they all try to put themselves where the mouse.target is. I want them to retain their model form and also I when I click I want the model to appear and the transparent clone is destroyed or even placed then the transparency is changed.

local player = game.Players.LocalPlayer

local mouse = player:GetMouse()

function Click ()

    local B = game.ReplicatedStorage.Headquarters

    local clone = B:Clone()

    clone:Clone().Parent = game.workspace.Buildings

    print "Cloned"

local part = workspace.Buildings.Headquarters

for i,child in pairs (part:GetChildren())do

mouse.Move:connect(function()
    if mouse.target then
        if mouse.target~=part then
            child.Position = Vector3.new(mouse.hit.p.X,mouse.hit.p.Y,mouse.hit.p.Z)

        child.Transparency = .5

        mouse.Button1Up:connect(function()
            child.Position = (mouse.UnitRay)
        end)

        end
    end
end)

end
end

workspace.Outline.ClickDetector.MouseClick:connect (Click)

Any Help will be Appreciated! Thank you.
