Maybe you could explain what you are trying to achieve? If you are trying to have different sets of annotations show up at different times, then you can create different Captures within the Annotation Set. Each Capture is a view with a particular view angle and distance along with different hide/show settings of Reference Frames, Notes and such.
I agree with the Capture, that works very good within Catia. My issue is that we use a viewing software for our non CAD users. When the viewing software reads the Catia data, it does a great job with the annotations but I am looking to "group"/organize the notes so that they can be viewed by clicking the check box on and off.
I guess another option would be to add another label under the original Annotation Set. Can you create a new one and add notes to it?
I hope that explains what I need, just thinking how to get there.
