Sometimes it is necessary to turn the 2D geometries into 3D features using on an elevation model. This is especially true when you want the feature to interact with the surface (e.g. burn building footprints into the terrain) or use them in 3D spatial analysis.
The new 2Dto3D template shows the process of creating 3D features from 2D using an elevation model. The data used in this template is a subset of the buildings available in the Virtual City template.
