Motion study

Hi all

I'm doing an animation on an assembly.
I would have liked to know if it is possible to change the configuration of an assembly or a part in the animation and if so, how.
I tried by inserting a key, but a priori it doesn't work.

Anyone have an idea?

Thank you in advance

Frédéric

By playing with display states?

Thank you #stefbeno for this test, but not transformed... I didn't succeed.

I finally solved my problem by doing a video editing post "Motion study".
