Thanks for the quick reply! I did use Positioner to record the initial position of the whole structure, but as soon as I opened Animator the roof got up above again.

Hello! I have the same problem. I created an animation with Animator (v4.5a) two days ago, it worked fine. Today when I opened the file to make adjustments, parts of my model (the roof) had moved up, and the animation no longer works. When I move the objects down where they should be (the roof should be on top of the structure like so), and then go back in Animator, it seems the position changes I just made are cancelled. I’m uploading the file as well as a screenshot of the desired shape. I should say that I’m using the trial version of SketchUp Pro 2025, which seems pretty unstable, on macOS Sonoma 14.4.1 (23E224), Apple M1 Max, 64 Go. I would be grateful to anyone who can offer a solution! Thanks
