How do you add a rotation feature to a model?

Hello. So, I have it when you select a tool, a model will spawn that lets you freely place it on your claimed land. It works perfectly. But now I need rotation.

How do I add a rotation feature using the R key?

Ok, so you need two things here.

• how to do something on r press

• how to rotate a model

model = something:FindFirstChild("Whatever").Anything

for q=1,360 do
	model:SetPrimaryPartCFrame( --you'll need a primary part
		model:GetPrimaryPartCFrame()* --the current cframe
		CFrame.Angles(math.rad(1),0,0) --rotate
		)
end

I'm assuming you already know how to do things when you press a key, but if you don't, tell me in a comment.

As for the r pressing, do that like this.

game:GetService("UserInputService").InputBegan:connect(function(key)
	if key.KeyCode == Enum.KeyCode.R then
		--do some rotate stuff
	end
end)
