Not sure what data the file contains but have you tried creating a point cloud? Lidar data is usually ASCII format and you can import that using point clouds.
You may be able to import that way, create a surface and export points as XYZ if neesesary otherwise you'll need to convert the file to an .XYZ file (ASCII to XYZ?)

Post a couple of lines from the file so we can see what format it's in.

It's likely a ESRI ASCII Surface. If you drag/drop it into a notepad the first lines should look like this:
ncols 200 nrows 200 xllcorner 119000.00 yllcorner 158000.00 cellsize 5.00 nodata_value -999999
Try creating a surface in Civil3D, then under the Definition, DEM Files, choose Add, the use the button in the upper right. Under the "Files of Type" you'll find the format.

The DAT extension is used by many applications and isn't a standardized format that I'm aware of. Post the file as an attachment and we will see if we can make any recommendations.
That is an ESRI GEN file and it appears to be in Lat/Long for islands of Maluku. Here are the options as I see them.
A) Do some fairly significant editing in an ASCII Editor, the first step will take the most time.
- Change each sequential ID number to PLINE
- Find/Replace single space to nothing.
- Find/Replace END to nothing.
- Save with .SCR extension.
- Draw with AutoCAD's SCRIPT command.
B) If this is a one time problem, zip the file and email it to me at dotson [at] dotsoft [dot] com, I will send you a DWG file.
C) If this is regular occurance, consider acquiring MapWorks Base, which will read this and numerous other formats.
