How To Tween PrimaryPartCFrames

The title is quite self explanatory.

How do I tween PrimaryPartCFrames? What I’m trying to make is a Podium Model which moves up (through TweenService). It’s a model, so I’m quite struggling with tweening it. Please help me do this.

I followed the same article and works perfectly.

Basically, you set a Primary Part for your model, weld all the other parts to that and then run the tween against the Primary Part.
