Hello Fredo,

Thanks for looking into this.

The problems on quitting are bugsplats. I started not reporting them because they were happening so often. Is it better to keep reporting? Let me know if there’s anything I can do to help further.

I have to do a number of similar animations for my project so I want to clearly understand your message. Several questions…

I tried to run the file you sent but it won’t animate. How can I fix this?

What do you mean by “making the movement hatched when played interactively”.

I need to show the spring motion decelerate (or accelerate for other cases later). Having 4 spheres allowed me to show constant motion as the spheres approached from a distance and then decelerated as the spheres interacted with the spring. Can I show constant motion and then deceleration with just 2 spheres? If so, how?

Would it be best for me to start this animation over? I think part of my problem may have been that I moved or renamed my file a few times. If I start over I’ll keep the same file name and location.

If the fix for Scaling will be in the next version of LibFredo6 should I wait for that before continuing to work on this?

Thanks for your help, David

Was this issue solved? My issue is similar. Movements and cameras I put in disappear when I re-open the file?

Thanks for the help. I have this working now.

I've been unable to export as a movie but I've exported as a file sequence that I turned into a movie using ImageJ.

A few issues are puzzling me:

1. I went back to further improve the cameras and found that they had disappeared. I'm sure I saved the file after I put the cameras in.

2. My exported images are cut off a bit. I'm not sure where to adjust this.

3. It isn't a big problem for me but SketchUp crashes everything I quit after using Animator.

In case you want to look at my file here's the link for the most recent version:

Additional point:
I just downloaded the file from the link above and found it is not working correctly. At least part of the problem is that both object movements and cameras keep disappearing and I have to replace them. So the animation works correctly at first but then does strange things when I replace object movements and cameras.

Thanks for looking at this for me. I keep working at it based on what you said.

Thanks. Here's the link:

For some reason the file often changes the view to very distant.
Also the easing I used leads to a lag between compression and release of the spring but I think I can edit that later.

I’m working on an animation showing two spheres approaching and then then separating. When they are close I show a spring between them compressing and releasing to represent the physical processes that occur (work and energy). I have the basics set and am now trying to add in camera effects. I’d like the camera to follow the objects as they approach, showing a closer view of the spring as they rebound. However, when I tried camera extents, the starting position I selected for the spheres changes automatically for some reason. Not sure what I’m doing wrong.
