I have been having this problem for a very long time now and I usually fix it by restarting illustrator but that doesn't seem to be fixing it anymore. I enjoy having animated zoom on and I can't stand having a little box to use to zoom with. I go into my preferences and animated zoom is check marked yet I do not get the animated zoom. I try to restart it and nothing happens. It will change my zoom just at random times while I'm drawing and its gotten to the point where I can't have animated zoom at all and rendering me useless when it comes to drawing. I've heard if there's not enough space on your pc then it will not let you use animated zoom but I have plenty of free space. Can someone please help me get my animated zoom back?
Which graphic card? I the driver up to date? Or has it recently been automatically updated?
How large is the file?
What's in the file?
Does that happen with all files?
Have you tried resetting your Illustrator preference files?
To do so:
For Macintosh Users: With Illustrator closed launch a Finder Window in column view and click on your home folder. With the Option Key pressed choose Library from the Finder Go Menu. Within the Library folder find the following two files and delete them: “Adobe Illustrator <Version #> Settings” (earlier versions of Illustrator might just say “Adobe Illustrator”) and “com.adobe.Illustrator.plist”. When Illustrator is next launched it will create new preference files and the program will be restored to its defaults.
After you’ve reset up the program (make sure that no document window is open) to your liking, it is a really good idea to create copies of your personalized “mint” preference files (make sure that you quit the program before copying them—that finalizes your customization) and use them in the future to replace any corrupt versions you may need to delete.
For Windows Users: Hold down Ctrl + Alt + Shift when launching Illustrator and respond affirmatively when asked if you want to reset.
Oftentimes, something that has worked in the past but is not working now can be restored by bringing Illustrator back to its defaults.
When resetting preferences a lot of settings get lost.
So I would try everything else before doing it. But that's just me.
Which is why in the instructions that I wrote, and use each time for recommending preference restoration, I have included the suggestion to create a copy of the preference file from when it is pristine to keep for future use. I fully recognize that, in this case, it may be a GPU issue since it is involved with animated zoom but the questioner seems to be saying that at one time the feature was working correctly but doesn’t now and that is the criteria under which I offered the recommendation.
Monika, I just want to say that in the just over two months since I was asked to participate in these forums I am astounded at the depth of your knowledge about Illustrator. Your retention of so many, sometimes obscure, characteristics about the features is amazing. For my own part, I have been working with Illustrator since 1989 (back when you couldn’t even work in Preview mode) and have been writing papers for the advertising agency I work at in New York about all of the upgrades that have come out over those years and have worked with it on a daily basis but still will find myself occasionally thinking OMG I had completely forgotten about that when I see one of your solutions.
I hope that I can be even a fraction as helpful in these forums as you have been.
That DID worked and it didn't deleted my settings (I guess)...
However really make regular backup updates to your settings just in cases and do NOT rely on good luck!
Change preview on CPU to preview on GPU. Its on View> Preview on GPU.
