Mike,

I try your suggestion but maybe i'm missing something,

I selected the plain and did the GROUP command, then selected the new group and created a CV curve and From animation menu selected "attach to path" (dont remember the exact command)
so now it moves on the curve automatically, now i move the group where i wanted tilted and set the key, thats when i loose all the movement and attchment to the curve....

any ideas?

Thanks!
