How to correctly orient a model with :GetPivot() and :PivotTo()

[sharksygame]

I have a flip car script and it lifts the car 20 studs and rotates it upright. it works fine in theory, but due to the model’s weird position situation, I seem to be rotated into the ground by several hundred studs. I still end up upright though. When I select the model mid play with move tool on, I can see that It registers the origin point, or position of the model to be where I spawned it in from. Is there a way to move the origin point with an unanchored model? because it ruins the orientation of the flipping.

This is the script I use to flip the car.

game.ReplicatedStorage.Flip.OnServerEvent:Connect(function(player: Player)
	local Model = player.Character.Humanoid.SeatPart.Parent.Parent
	local CarBase = Model["Car Base"].CarBase
	local AngleX = -(CarBase.Orientation.X/20)
	local AngleZ = -(CarBase.Orientation.Z/20)
	for i = 1,20 do
		task.wait()
		--CarBase.Orientation += Vector3.new(AngleX, 0, AngleZ) < this was a previous attempt to orient the car, ignore it.
		Model:PivotTo(Model:GetPivot() * CFrame.Angles(math.rad(AngleX), 0, math.rad(AngleZ)))
		Model["Car Base"]:PivotTo(Model["Car Base"]:GetPivot() + Vector3.new(0,1,0))
	end
end)

Not 100% sure whats wrong with the math but you can “override” the position of a CFrame by subtracting its current position (Vector3) and adding a new one. That might let you work around this.

Can you explain further? The math for rotating and moving works fine, but I just want to know how to counteract the issue where the models actual position is not where the car really is.

[azqjanna]

If you take a CFrame and subtract its own position, which you get from cf.Position, and add a new position, you will have the same rotation but at the new position. That does what youre describing:

newCf = cf - cf.Position + desiredPosition

You can pivot to this newCF.

oh, that makes sense. but wouldn’t that move the things inside the model too? or would it just move the model itself.

[azqjanna]

If you set the CFrame of something it also moves everything that is attached.

That’s what I thought, but I mainly just want to fix the models position to be inside the car, so it rotates correctly during the flip. would I just take everything out of the model ,change the position, and add it back?

So it turns out I got it working using your strategy, thanks for the help.
