Editing 3D Annotations in NX
A modification in 3D annotations (nominal value, tolerances, display type, etc.) is applied on save. When an annotation is deleted in NX, the associated model item is not deleted in Windchill, but it is disassociated with the model upon save.
You can edit the annotation subtype to create a new model item with the same subtype by following these steps:
1. Un-designate the annotation and save the model. The model item is disassociated.
2. Re-designate the annotation and upload the model. A new model item is associated.
