With the release of MicroStation V8i SS3 you can publish non-graphical business items to a 3D PDF document. These business items appear as objects in Adobe Reader’s Model Tree.
By default, business items are not included in the published 3D PDF document. You must take additional steps to include the business items. To include business items in a 3D PDF document use the 3D Plotting Options dialog.
To include a subset of the business items contained in a 3D design file, you must create a Property Filter file using the property Filter dialog and specify this file in the 3D Plotting Options dialog.
