Hi,
There are issues with saving the 3D PDF files with comments in Adobe which are created using Autodesk Inventor.
While annotating the 3D pdf with 3D comments in Adobe Acrobat Pro, it only saves one comment. You can put all the comments in and save the file but when you reopen it, only the 1st comment is saved in all the 3DCommentViews in the model tree.
As per Adobe Support, the issue is with Anark Pdf Files as it works as expected with other non- Anark 3D Pdf files so this needs to be improvised so the customers can reap the full benefits of this feature.
More than happy to describe the issue in detail if required.
A lot of people are facing this issue in the community so it needs some priority and focus.
Thanks,
Akshay
