Thanks Daniel! I think if you were to move the motion path in the 2nd image (from above) over the ball it will appear to be the same size as it was. I used grids to determine this. I may just be doing something wrong but it doesn’t appear to work for me.
This is the ball and path with 100% Scale…

Now I selected “Edit” and “Select All” and then changed the scale to 200%…

As you can see, the ball increased in size but the motion path did not.
I’m OK if this is a future enhancement thing or if I just don’t get it. We simplified the example here but in my project, the scenes are much more complex. If this worked and if it was possible, I’d have to group and change bounding boxes for all of my animations within the scene rather than simply grouping the entire scene. I was hoping that I was just missing something and could apply a global scaling of the scene. Thank you very much for your help!
