how do i cframe a model to move or rotate?

You can just use :SetPrimaryPartCFrame() method

But make sure to set it's Primary Part first.

------------------------------------

If you decide to instead use a iterator (for i, v) to loop through and rotate/move it. This is how to do it.

affectaccessories = true -- set to false if you don't want to affect hats but i added this just in case
model = game.Workspace.Model
for i, v in ipairs(model:GetChildren()) do
	if v:IsA("Part") or v:IsA("MeshPart") then
		v.CFrame = CFrame.new()
	elseif v:IsA("Accessory") and affectaccessories == true then
		if v:FindFirstChild("Handle") then
			v.Handle.CFrame = CFrame.new()
		end
	end
end
