[Closed] In coordsys object last rotation or direction

Hi

sorry for the title i don’t know what should i exactly call it.

when i say in coordsys world the rotation has no effect and we can move the object
when i say in coordsys local or gimbal based on the object’s rotation we can move the object but how about this :

I create 2 teapots to show what i’m looking for but actually it should be done with one object

A = teapot radius:13 wirecolor:orange lid:off handle:off 
B = teapot radius:13 wirecolor:Blue lid:on handle:on body:off spout:off

no_rot = eulerAngles 0 0 0
the_rot = eulerAngles 0 0 45 
animate on  at time 10 rotate A the_rot 
animate on  at time 10 rotate B the_rot

animate on  at time 10 in coordsys local A.pos.x =0
animate on  at time 10 in coordsys local B.pos.x =0
animate on  at time 30 in coordsys local A.pos.x =100-- the_rot 
animate on  at time 30 in coordsys local B.pos.x =100


animate on  at time 30 rotate A no_rot 
animate on  at time 40 rotate A the_rot

Now my question is after frame 40 how to move orange teapot in coordinate of blue teapot’s .or after frame 40 move orange teapot in coordsys of orange teapot’s coordinate at frame 30.
