Moving 2 parts together

i have this project where i need to change the cframe of part1 and its child part2.

part2 has to be on top of part1, but when i change the cframe of part1, part2’s cframe doesnt change, and i cant set it to be on top.

is it possible to make it so that all the children of part1 get positioned the way they were positioned before?

(i have tried using part1.position)

try using the weld constraint so part welds to the part1.and when part1 tweens,part2 will also move to part1 welded position too.
OR…
do 2 tweens because you cannot move a part and the parts children together.

nevermind, i fixed it by making it a model and using part1:SetPrimaryPartCframe() but thanks for the help :grinning:
