Is it possible to create a Rotation and Position tweens at the same time for a model?

Not sure, could be intentional but it could also be a bug, in the past I just worked around this issue through hacky means.

Guess its intended

Tweening Welded Objects

Looks like you’re tweening the Position property. This is the intended behavior for that property. Tween the CFrame property instead. Tweening the CFrame property will move the whole welded assembly together. Changing the Position, Orientation, or Rotation properties will update the values of any rigid joints to allow the part to move. They always did this for WeldConstraints, and used to do a “safe move” and destroy any other weld joints until we changed it to be consistent with WeldConstrain…

Scratch this, came up with something infinitely better,

local tweenservice = game:GetService("TweenService")

local model = script.Parent
local endcframe = CFrame.new(Vector3.new(0, 5, 0))*CFrame.Angles(0, math.rad(150), 0)
local TweenPositionInfo = TweenInfo.new(1, Enum.EasingStyle.Linear)
local TweenRotationInfo = TweenInfo.new(3, Enum.EasingStyle.Bounce)

local function TweenCFrameModel(model, endcframe, TweenPositionInfo, TweenRotationInfo)
	local disconnectevents = false
	local primarypart = model.PrimaryPart
	local startcframe = primarypart.CFrame
	model:PivotTo(endcframe)
	local endpos = primarypart.Position
	local endrot = primarypart.Orientation
	model:PivotTo(startcframe)
	for i, v in pairs(model:GetDescendants()) do
		if v:IsA("BasePart") and v ~= primarypart then
			local offset = primarypart.CFrame:ToObjectSpace(v.CFrame)
			local checkformovement
			checkformovement = primarypart:GetPropertyChangedSignal("CFrame"):Connect(function()
				if not disconnectevents then
					v.CFrame = primarypart.CFrame * offset
				else
					checkformovement:Disconnect()	
				end
			end)
		end
	end
	local postween = tweenservice:Create(primarypart, TweenPositionInfo, {Position = endpos})
	local rottween = tweenservice:Create(primarypart, TweenRotationInfo, {Orientation = endrot})
	postween:Play()
	rottween:Play()
	repeat task.wait()
	until postween.PlaybackState == Enum.PlaybackState.Completed and rottween.PlaybackState == Enum.PlaybackState.Completed
	disconnectevents = true
end

TweenCFrameModel(model, endcframe, TweenPositionInfo, TweenRotationInfo)

No buggy welds, lerp:(), or hacky animation nonsense needed, even works on the server properly unlike my last attempt with welds.
This took me a lot longer than it should and quite frankly I should have figured this out sooner, but hey its here now.

EDIT: As I am testing this I realized that if you run it on the server it looks a little choppy from the client, and running the code in a localscript seems to fix the lag but, again, it won’t replicate. To be honest I still believe this is most likely your best approach to this quite unique problem,

so I would probably recommend a system (Probably a remotevent) for the server to tell the clients to tween the model and the server would simply just have to update the model on the server to the end position when it finishes.

Otherwise you could keep the tween on the server and simply deal with the lag if you choose that.

Whatever you choose or whatever other solution you come up with I hope this has helped you enough!

I’ll check this out later today, by taking a brief look at the code I think it might for me!
Will update the post when tested, thanks for your help.
