Unfotunately ArcScript You mantioned, doesn't work with AG 10 😞 Do You have any solution ?
I am not sure if this would work for you or not (depends on your 3DS model). Here's what you can try: - Import your 3DS model into ArcGIS as a Multipatch. - Convert multipatch into point feature using Feature Vertices to Points (requires ArcInfo)- Create a TIN from point feature that are converted from multipatch. Attached are some example on when it works and when it will not.
