Hi,

i want to create a animation of a bar which is l-shaped & kept at a certain height. the bar is to be introduced in to another bar of l-shaped.

actually i want to move & rotate the bar with respect to some position, but at the moment when i update the size of bar the distance to move & angle to rotate will be updated automatically.

example: when the bar is of 80mm height the bar should move 80 mm below. but if i change the bar to 60 can it be automatically updated to 60mm moving distance, how to do it?

please suggest?
