After running the command, the user is prompted to select a surface to work from.

A dialog is presented upon surface selection, where the user can select or define an optional outer boundary for the new surfaces. A Surface Style can be selected for all the new surfaces.

A list of elevations and surface names can be provided by the user. Polylines will be extracted from the surface at the given elevations. If multiple polylines are created from various low spots in the surface, they will be used as boundary data, provided that the polylines are closed.

Elevation/name rows can be added and removed easily. The table can be sorted by name or elevation.

An optional log is available for viewing the steps taken, which may help troubleshoot any issues during the extraction and creation process (for example, if an elevation is not available on a surface, it will not be extracted).
