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. I need to add buildings to DEM. The roof of the buildings are precise (attachment). I need to creat some solar shading analyses and I'm using AG 10 with all extensions. Data that I collected are: 3D buildings layer (3D layer) witch I convert to multipatch, contour of the terrain, boundary of the terrain, polygon trees layer with height. I create DEM from contour, it's resolution is 0,5 m. You have any idea how I can 'add' buildings to DEM and get DSM? I will try to use Your tips, mabe it helps.

Mabe You have any idea how I can analize 3D buildings to get information about slope, aspect etc. of the roofs?

There is no direct conversion from Multipatch to TIN. What I was trying to emphasize earlier is that you can use the multipatch you create in some of the 3d tools. There is an ArcScript Tool and an enhancement request that is currently among the ideas to be considered in the future. Currently you cannot do it with out of the box tools. Unfotunately ArcScript You mantioned, doesn't work with AG 10 😞 Do You have any solution ?

Hello! I need some help with my project. My english isn't perfect, so I apologize in the begining for any mistakes:) I need to creat some solar shading analyses and I'm using AG 10 with all extensions. Data that I collected are: 3D buildings layer (3D layer) witch I convert to multipatch, contour of the terrain, boundary of the terrain, polygon trees layer with height. I create DEM from contour, it's resolution is 0,5 m. I was trying to use http://arcscripts.esri.com/details.asp?dbid=15173 by it doesn't working on AG 10 😞 Do You have any idea how I can 'add' buildings to DEM and get DSM. I need to add, that roofs of the buildings are precise (attachment). Do You have any suggestions what I can do? I would be very gratefull!
