Generating the feature list

Earlier in this tutorial, you made maps of the location and type of trees, geovents, and other features. However, in the SMF (Spring Map File), the position of trees, geovents and other features are written not as maps, but as one long list. To convert these maps into list for the SMF exporter, use the 'Generate feature list' button in the Spring Mapping Wizard, highlighted below:

After you do this, L3DT will inform you of how many features were found, as shown below. Please note that this number actually includes the number of trees, geovents and features.

The next step is preparing the SMD settings.
