To complete this exercise, the following software and data are required Some familiarity with Google SketchUp may also be helpful. It's assumed that the reader is familiar with ArcGIS Desktop applications and the ArcGIS 3D Analyst extension, including ArcGlobe. The workflow outlined will familiarize the reader with tools in ArcGIS 10 for importing, exporting, and placing different types of 3D features. It uses a geometrically simple urban feature-a freeway overpass in downtown Philadelphia-and starts with a polygon and some high-resolution aerial imagery. This exercise walks the reader through the process of creating and adding texture to a 3D multipatch feature. ArcGIS 10 introduces a host of new 3D data management and analysis capabilities that enhance 3D analysis. The multipatch, Esri's native 3D feature type, is a key element whether working in ArcGlobe or ArcScene. The 3D virtual city is emerging as an essential GIS tool for visualization and analysis in the urban environment-from placing a proposed building construction in the context of its surroundings to conducting analyses in three dimensions such as line-of-sight or 3D volumetric shadows.

The Result By following these steps you can bring your model back and forth between the two programs.Figure 1: This exercise shows how to correct this sampling error, commonly seen in high-resolution DEMs in urban environments. ***Note you will add the same model over and over again with ever click until you deselect the “Insert Tool”
When prompted, navigate to the location of the supported 3D model file on disk. 
Click the desired location of the multipatch model in the 3D view. Select the Insert tool under Construction Tools. The Insert tool will appear in the Construction Tools window. Click the multipatch feature in the Create Features window. Click the Edit Placement tool on the 3D Editor toolbar. Begin a 3D edit session by clicking the 3D Editor drop-down and click “Start Editing”. Add an empty or populated multipatch feature class into ArcScene or ArcGlobe. Name the File something relevant and save it in a familiar directory as a COLLADA. Returning to ArcScene Getting the model back into ArcScene is almost the exact opposite first we want to export our finished model in Sketchup by “Selecting” File > Export > 3D Model Be sure to group all elements before saving. Rendering tasks Perform all necessary rendering tasks. Here you will want to decide if you want to merge coplanar faces – typically for texturing the outsides of builds you do want to merge. Navigate to where you just exported the Collada file from ArcScene and make sure your file type is COLLADA in the drop down menu. Open Google Sketchup® and choose a template that is in the same units as your projection in ArcScene (i.e. Convert to Collada Again in the ArcToolbox > Conversion > To Collada > ‘Multipatch to Collada’ tool is what we will use to output a file in a format Google Sketchup® will recognize. Input the corresponding Feature layer to be converted into a Multipatch, put it in a familiar directory for output. “Layer 3D to Feature Class” is the tool we will use toĬonvert the extruded features to a ‘Multipatch’ feature class. In ArcToolbox > 3D Analyst Tools > Conversion >. Visually inspect extruded features in the Dataframe. (You can also select and/or construct attribute expressions using the ‘Expression Builder’ button) Check the box and then either extrude feature by a. “Select” ‘Extrusion’ tab on the Layer Properties. “Select” = ‘Properties…’ (very last option) “Right Click” on the layer in the Table of Contents ->. Add your polygon data from shapefile, geodatabase, or SDE connection.
