2007 LLD to 2013 C3D points conversion
I was forced to switch from AutoCad 2007 Land Development Desktop to AutoCad Civil 3D 2012. The problem I have is that C3D 2012 does not recognize the LDD 2007 points database. How does one load a drawing from its LDD project with C3D and have the points register correctly.
LDD has an drawing orientation setup where an AutoCad world coordinate is given a project Northing & Easting. For instance, (0,0) is stored as a local coordinate of N:5K,E:5K. LDD 2007 used COGO points which were converted Softdesk point blocks with attributes. I??m not sure what C3D uses for points and database. I find it difficult to believe that Autodesk did not allow for a backwards compatibility with older projects.
I did manage to load a 2007 drawing and do a conversion of AutoCad points in the drawing and they showed up in a listing of points. It assumed the local N&E were World coordinates and removed the points from their original drawing location to a location 5,000 feet away.
How do I load these old drawings with their coordinates intact?
