using 2013 and attempting to connect to a DEM downloaded from LSU Atlas. I get the "Failed to open FCO connection. Could not open/read from file" Any suggestions? Am wanting to generate a watershed from the DEM surface.
I went to http://atlas.lsu.edu/dem24k/ and downloaded the Larto Lake South (USGS ID:....31091C8) DEM.
1st attempt: Data Connect in AutoCAD Map 3D 2013 -- no warnings or errors, but I couldn't see the image. Zoomed extents and Resampled Raster with still no results.
2nd attempt: Data Connect in AutoCAD Map 3D 2014 -- image came up
3rd attempt: Data Connect in AutoCAD Map 3D 2013 -- image came up
In all cases, the DEM's coordinate system (UTM27-15) was automatically applied to the new drawing.
So I'm not sure why the 1st attempt turned out the way it did, but I'd just try again if I were you.
(I never got a Failed to open FDO connection message).
You might also try right-clicking the shortcut to AutoCAD and Run As Administrator.
Let us know how it goes. Thanks
Thanks for the reply. I had always downloaded the DEM from the LIDAR button rather than the 1:24000 DEM. I did connect to the data, but the task manager was ghosted and i couldn't generate any contours. The size of the DEM is much smaller than the LIDAR one. This would be useful to drape images over for display. Thanks for the heads up.
