How To: Convert a 2D shapefile to a 3D shapefile
Instructions provided describe how to convert a 2D shapefile to a 3D shapefile using the ArcGIS Desktop 3D Analyst extension.
- Verify that the 3D Analyst extension is turned on by navigating to Tools > Extensions. Check 3D Analyst if it is not already checked.
- On the 3D Analyst toolbar, click '3D Analyst' and navigate to Convert > Features to 3D.
If the 3D Analyst toolbar is not visible, navigate to View > Toolbars and select 3D Analyst.
- Select the 2D shapefile as the input feature.
- Select one of the three options for the 'source of height' of the 3D shapefile:
· Raster or TIN requires a raster or TIN dataset that contains elevation values.
· Input Feature Attributes requires a field in the input feature class that contains elevation values for the features.
In order to see the field in the tool, the field data type must be a number.
· Numeric Constant is a constant z-value that is applied to all the features.
- Specify the location of the 3D shapefile in the 'output features' box and click OK.
