A snapshot is a surface operation that captures the current state of surface.
- In Toolspace, on the Prospector tab, expand the Surfaces collection, right-click the surface, and click .
The current surface points and triangles resultant from previous surface operations are contained in a surface snapshot operation. When a surface is built, previous surface operations are ignored and the surface build begins at the snapshot operation. Surface operations that are included in the snapshot are marked with 
in the Prospector tree.
Snapshots can also be created automatically. A LandXML setting enables you to specify that a surface snapshot be created in the surface definition subsequent to the importing of a surface when using Import LandXML. For more information, see To View and Edit the LandXML Import Settings.
