Welded parts won't tween!

Hello!
I once tried to tween a part that had stuff welded to it but only the part tweened and not the other parts welded to the tweened part


as you can see, the sphere has been tweened but the other parts that were welded to it weren’t

here are the welds

You’ll need to use a cframe to move the entire model with a tween. Only moving the main part using a tween will just break the welds. This would be possible without cframes if you were using velocity.
