I am not able to find Assemble option and Animate key frame editor in Creo Illustrate 3.1.
I can see Animation tab, but the control tools within tab are not highlighted.
The tools tab does not include assemble option
Please find the attached file for your reference
Thanks in advance
I downloaded and installed Creo Illustrate 3.1 M010 and I can see following window. I suggest you uninstall Creo Illustrate on your PC and repeat my steps.
