The video below illustrates the Export to KMZ functionality in the Sincpac-C3D.
This feature allows you to export Cogo Points to a KMZ file (a compressed KML file),
which may be opened in Google Earth. During the export, you may select a mapping
file, which maps your Civil 3D Point Markers to your own custom images, so you have
a great amount of control over how your points appear in Google Earth.
The tasks shown in this demonstration require the Points module of the Sincpac-C3D,
and may be performed in any version of Civil 3D, 2008 and later.
