The convert Land Desktop points feature is not really new to Civil 3D. This utility could be downloaded from the Autodesk Support website under the Utilities & Driver section.
In the 2007 release this conversion utility was added to the Points menu, located under Utilities. After selecting the "Convert Land Desktop Points" option, a dialog box will appear prompting you to select parameters to apply to the new Civil 3D Point objects. You can set a variety of point settings such as, default layers, point creation settings, default styles, default name format, and point identity. Users can also select a default point group to which these points will be applied. There is also a check box to indicate if the original point layers are to be preserved enabling us to transfer directly from LDT to Civil 3D.
This command provides another layer of functionality for getting point data into Civil 3D from Land Desktop. Some other transfer methods would include XML import/export, importing Land Desktop Data, and exporting/importing of points. Some care should be taken to preserve data integrity. If you are planning on using your file in Land Desktop, there is no utility to convert back to Land Desktop Points.
