How to tween model rotation and position independently

I tested and i have to tween cframe because the rest of the model doesn’t follow if i tweened position instead even though its welded

i have it so it rotates when i press r
but when i move the model the rotation gets reset
also if i spam r the rotation gets messed up for some reason

--code for rotation
	if input.KeyCode == Enum.KeyCode.R then --rotate model
		local tween = TweenService:Create(model.PrimaryPart, tweenInfo, {CFrame = model.PrimaryPart.CFrame * CFrame.Angles(0, math.rad(90), 0)})
		tween:Play()
		return 
	end

--code for mouse position
        local raycast = getRay(input.Position)
		if raycast then
			local tween = TweenService:Create(model.PrimaryPart, tweenInfo, {CFrame = CFrame.new(raycast.Position)})
			tween:Play()
		end

What about instead of using Tweens for that task, just use RunService.RenderStep and change the current CFrame position and rotation over time independently with mouse and R key?

Interesting way to put it, however that wouldn’t equate to having easing in/out tweening motion, then with runservice it would all be linearly

Totally agree with that. Thats a reason why I still using Tweens on many projects. But, in your case I sense that the amount of Tweens created per movement of mouse could be a little intensive, so trying RunService/Lerp approach could be helpful.

Specially when its possible to simulate Easing style/direction when using RunService and Lerping CFrames. For example check this Module which creates the easing by using lerp

If you just divide the timeElapsed by the totalTime, you will get a number between 0 and 1 which can be passed to tweenService:GetValue. This can be used to get easing styles easily without writing your own easing funcs/using a module.

There is no direct way to rotate a model using tween service, I would suggest checking this out.
