Hello,
In regards to the status of 3D widgets, they are currently experiemental, which means that there are definitely going to be some rough edges when working with them. There are currently more than a few known issues regarding 3D widgets, so if you’d like to go into more detail about the exact issue(s) that you are running in to, I’d be glad to look into this for you.
Have a great day,
Sean Flint
