Object moving irrelative to given path urgent help

I am trying to animate contruction of a high rise tower. On screen all object are in proper positon when I jupm from one keyframe to another. But when I run animation they have moving totally different. I noticed a problem when I copy paste new objects. that they did not move to their expected location. but I moved them while animate was closed.

But when I try to animate they still move erratically where ever they want. Is there a solution for this.

Help will be gratly appreciated.

I have had similar experience with copy-and-pasted geometry. If you’re using a proxy, you might want to make another proxy for the new (copied) geometry. Also, make sure to break the reference to any old parent-child relationships just to be sure.

The new copies are probably jumping because they have maintained some of the original geometry’s animation data.
