I export as *.dem from global mapper and use that to build the surface. Make sure your projection matches the one used in C3D. Create the surface and add the dem to it instead of creating one from a dem.

Sanet,
Civil 3D has a little problem with DEM data. It uses the lower left of pixel instead of center. DEM is derivative data. Better to use the original LiDAR point cloud data.
Location? I'd try first to find state or county elevation data.

@Pointdump
Hi,
Thank you very much for the information you sent. I got the lidar data. The coordinate system of my cad drawing is NAD83 Georgia State Planes, West Zone, US Foot (GA83-WF). But when .laz is converted to .rcp through autocad recap and imported into civil 3d, it is displayed in a different place. (When importing to civil 3d, I also imported according to "use geographic location".)
please help.

Sanet,
What did "Current" and "Target" look like when you brought the point cloud into ReCap?
The LAZ file I grabbed was horizontal degree units and vertical Meters. ReCap read the header information as "LL-HPGN".

Sanet,
Horizontal transformation worked well on the LAZ file I grabbed. You'll need to check vertical units to see if they are OK.
Attached are drawing, ReCap files, and the original LAZ file. I filtered ground points in ReCap.

Civil 3D inserts the DEM the same way it inserts all rasters, i.e. the lower left of each pixel. However, if you add the DEM as an FDO connection, then it inserts properly. (It treats the raster as an entity, not as a collective bunch of pixels.) As long as the raster is a rectangle and not an IRREGULAR shaped image, such as one with zig-zag edged(s), an FDO will insert correctly.
