Global Mapper User's Manual
The 3D Line Export, 3D Area Export, and 3D Point Export sections allow the user to control whether or not
area, line, and point features with elevation values associated with them are drawn at the terrain surface or at
the elevation values associated with the feature. You can specify whether the elevation values are relative to
ground level or sea level if drawing the features above the terrain. If area features are drawn above the terrain,
the Extrude Areas option allows you to control whether or not they will also be extruded, which means they
will extend back to the terrain surface, making them look like solid 3D features. If this option is not checked,
the areas will just be drawn in space as a surface and not a 3D closed object. If the Fake 2D Area Heights to

values in order to attempt to get them to layer properly when displayed in Google Earth. This is only
