3D Annotations VS 3D Annotation Features

Hi all,

you can create a 3D annotation as a text with leader or a gtol, and this kind of thing is visualized at the top of the model tree.

Next, you can create a 3D annotation feature, in which you can create a set of all the annotation (gtol, finish surface symbol...)

What is the logic that guides you to prefer one way instead the other one?

What is the advantage in using the first method or the second one?

PS: I use WF5.

Thanks.

Regards
