In the current functionality, you are able to attach custom attributes to the 3D Model, which are automatically transferred to the related EPM document in Windchill.
The 2D Annotation drawing, is also saved to a seperate EPM Document.
The functionality to transfer an attribute to the Annotation document is missing. So you cannot attach e.g. "Frame Size" or "Scale" or "Drawing Type" attribute to the Annotation drawing, so these attributes cannot be passed to the related EPM Document.
Some customers often use this kind of attributes to supply a frame size (necessary for output reasons), or a drawing type ("laser", "folding", ...).
