[wptabs style=”wpui-alma” mode=”vertical”] [wptabtitle] Getting Started[/wptabtitle] [wptabcontent]

• Open ArcScene
• Add your polygon data from shapefile, geodatabase, or SDE connection
• “Right Click” on the layer in the Table of Contents ->
  “Select” = ‘Properties…’ (very last option)

[/wptabcontent]
[wptabtitle] Extruding Features[/wptabtitle] [wptabcontent]

• “Select” ‘Extrusion’ tab on the Layer Properties
  Menu
• Check the box and then either extrude feature by a
  set value or pre-determined expression. (You can also select and/or construct attribute expressions using the ‘Expression Builder’ button)
• Visually inspect extruded features in the Dataframe
  and ensure they look to be correct.

[/wptabcontent]
[wptabtitle] Convert to feature class[/wptabtitle] [wptabcontent]

• In ArcToolbox > 3D Analyst Tools > Conversion >
  “Layer 3D to Feature Class” is the tool we will use to
  convert the extruded features to a ‘Multipatch’ feature class.
• Input the corresponding Feature layer to be converted into a Multipatch, put it in a familiar directory for output.

[/wptabcontent]
[wptabtitle] Convert to Collada[/wptabtitle] [wptabcontent]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.


[/wptabcontent]
[wptabtitle] Import to Sketchup[/wptabtitle] [wptabcontent]

• Open Google Sketchup® and choose a template that is in the same units as your projection in ArcScene (i.e. meters, Feet and Inches, etc.)
• In Sketchup > File > Import…
• Navigate to where you just exported the Collada file from ArcScene and make sure your file type is COLLADA in the drop down menu
• “Select” > Options…
• 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

[/wptabcontent]
[wptabtitle] Rendering tasks[/wptabtitle] [wptabcontent]Perform all necessary rendering tasks. Be sure to group all elements before saving.[/wptabcontent]
[wptabtitle] Returning to ArcScene[/wptabtitle] [wptabcontent]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

• Name the File something relevant and save it in a familiar directory as a COLLADA .dae file
• Add an empty or populated multipatch feature class into ArcScene or ArcGlobe.
• Begin a 3D edit session by clicking the 3D Editor drop-down and click “Start Editing”.
• Click the Edit Placement tool on the 3D Editor toolbar.
• Click the multipatch feature in the Create Features window.
• The Insert tool will appear in the Construction Tools window.
• Select the Insert tool under Construction Tools.
• Click the desired location of the multipatch model in the 3D view.
• When prompted, navigate to the location of the supported 3D model file on disk.
• Select the model and click Open.

***Note you will add the same model over and over again with ever click until you deselect the “Insert Tool”[/wptabcontent]
[wptabtitle] The Result[/wptabtitle] [wptabcontent]By following these steps you can bring your model back and forth between the two programs.
