Add Contour Lines to a Toposurface

In some cases, you may need to add contour lines to a toposurface.  You may also want to control the way the additional contour lines are presented in your view.

You can accomplish this using subcategories of the topography category, and then making changes to the site settings.

1. Make the necessary subcategories of Topography in Object Styles.
2. Apply them in the 'Site Settings' dialog (little arrow next to 'Model Site' on the Massing & Site panel).

See the video for an example of this process.
