C-Frame a Model down?

I was going to C-Frame a Model so that it moves down, but not all the bricks are in the same Y Axis? Basically, I just want a whole Model to move down for about 3 seconds

Sorry I don't have a code, C-Framing with a Script isn't my thing, and I tried the Wiki but it only shows for one part.

For this you can use the MoveTo method or the SetPrimaryPartCFrame method.

First you gotta set the primary part, it can be any part you want.. just choose one random. Then you use the SetPrimaryPartCFrame to move the model down in a for loop.

local model = workspace.Model --Model to move
local part = model:GetChildren()[1]
model.PrimaryPart = part

for i = 1,3,.01 do
	wait()
	model:SetPrimaryPartCFrame(model:GetPrimaryPartCFrame() - Vector3.new(0,3,0))
end
