Global Mapper support import and export of meshes, lines, and units to and from the Aquaveo SMS application's .2dm files.

The following .2dm values are not exported: Time series data, boundary conditions, material properties, and global parameters other than units.

To convert the mesh to an elevation grid see Create Elevation Grid from 3D Vector Data
