How do you retrieve the initial display state of a model as the active doc? I have looked at 3DViews and DocumentSpecification and each time it processed the line, it only returned an empty string.

Set sw3DView = Model.Extension.Capture3DView

iDS = sw3DView.DisplayState

Set swDocSpec = swApp.GetOpenDocSpec(Model.GetPathName)

iDS = swDocSpec.DisplayState

iDS returns "" in both cases. Any suggestions?
