3D Models

[RuiPlácido]

Hi,

I'm new member in this forum and need help for use da 3d analyst.
It's possible in Arcgis 10 use directly 3D city models that can be loaded directly into ArcGIS?

I read in ESRI that option is possible.How?

"Easy Access to Existing 3D Data

The Web is rich with GIS data that can be accessed and used immediately. ArcGIS Online is a great place to access basemaps, imagery, elevations, and demographic maps for creating your 3D views. Esri CityEngine and Esri partners such as Pictometry, Blom, TeleAtlas, and VirtualCity provide ready-made 3D city models that can be loaded directly into ArcGIS"

This was read.

There is a blog that discusses 3d Virtual Cities here.  Also there is demo showing it in action here. 

What your quote is referring to is that it is possible to purchase data from those companies that can be used to display in ArcScene or ArcGlobe in 3d.  There is information through ArcGIS Online that can be utilized immediately, but for many of the multipatches and 3d objects, you must create them on your own or purchase them from a vendor.

Rui,

Esri products are only compatible with Google Sketchup v6, but not higher versions.  In Sketchup, you can save your model to a previous version.

Ok. With google sketchup pro 6 it's possible do this process?
Could put by steps how to do?

Thanks for help.

Rui,

Open your model in Sketchup v 8 and save it to version 6. Go to Sketchup's File Menu > Save As.  Sketchup does not 'Export' to ArcGIS.  ArcGIS simply reads Sketchup files if they are v 6 or earlier (depending on your ArcGIS version).  There are two things you can do.  1) Symbolize a point with your model, which is especially helpful if your model has no spatial reference.  2) Run the Import 3D Files geoprocessing tool to convert the model to a geodatabase multipatch feature class.

ok. thanks. But in google sketchup 8 I export model 3d for file Model.dae . I don't understand for that you need  a multipatch and how do I create.

[JeffreySwain]

If you are exporting the sketchup model as a .dae, then there are three ways to import it in ArcGIS.  You can create a point and then import the 3d symbology, create an empty multipatch feature class in a geodatabase and then insert the multipatch manually or you can use the Import 3d Files tool. The .dae cannot be added directly, you have to import it one of these ways.
