Coordinate Transformations:
Assumed Coordinates to Project Coordinates

In this demonstration, the drawing uses a Project Coordinate System.  The Project Coordinate System is linked to our Grid System by a combined scale factor.  Then we acquire some additional data, collected in an assumed coordinate system, and we wish to import this additional data into our Project.

If you are new to coordinate conversions in Civil 3D, it may be helpful to watch the video on converting Project Coordinates to Grid Coordinates before watching this video.  There is also an article on the Edward-James Surveying website, Coordinate Transformations in Civil 3D, which goes into extensive detail about the Transformation Tab.

The tasks illustrated in this demonstration may be performed in any version of Civil 3D.  However, this demonstration was performed using Civil 3D 2010, and there may be some variations in other versions of Civil 3D.
