How does one rotate a Model using a script?

Let's say I am displaying a model, and I want the whole model to rotate slowly on an axis. Or in another case, I am trying to make an animated creature in which it's arms/legs move as a model. Is there any algorithm or function I can use to achieve this? Help would be appreciated, thanks you.

CFraming a model is no problem. Besides, the idea is simple, isn't it. The big issue is getting the right relation. What I mean by this is, you have to have to some base to how you want it rotated - what to rotate based on (or change the CFrame at all).

What I've done is make this function get all the parts in a model (descendants too) and pick the first part in the table to use as the "basis." What happens is that all the CFrames are saved in relation to this "base" part. It uses the difference between angle/position. So if one part was 3 studs to the right, and 30 degrees angled in respect to the main part, then it will stay that way when the main part is moved/rotated. So, obviously, if the parts always stay the same in respect to the main part - they will seem to "rotate/move as a model."

function GetAllPartsInModel(M)
	local AllParts = {}
	local function Grab(Ancestor)
		for i,v in pairs(Ancestor:GetChildren()) do
			if (#v:GetChildren() > 0) then
				Grab(v)
			end
			if v:IsA("BasePart") then
				table.insert(AllParts, v)
			end
		end
	end
	Grab(M);
	return AllParts;
end

function SetModelCFrame(Model, NewCFrame)
	local Parts = GetAllPartsInModel(Model);
	local CFrames = {};
	local MainPart = Parts[1]
	for i,v in pairs(Parts) do
		if i > 1 then
			CFrames[v] = MainPart.CFrame:toObjectSpace(v.CFrame)
		end
	end
	MainPart.CFrame = NewCFrame
	for i,v in pairs(Parts) do
		if i > 1 then
			v.CFrame = MainPart.CFrame:toWorldSpace(CFrames[v])
		end
	end
end

SetModelCFrame(Workspace.Model, CFrame.new(0,10,0) * CFrame.Angles(0,1.5,0))
