AutoCAD Map 3D

[#1]

I'm using Map3D & Raster Design 2012.

I have connected to some SRTM DEM data, but the resulting terrain and contours I generated are not showing properly. Specifically, the map area is stretched out of shape (too wide L & R). I seem to recall it had to do with setting the proper "define coordinate system" option for the file.

Can anyone provide me with any help on what to assign, or if I'm off the mark altogether?

Thanks in adavnce for the help.

I fear you can't transform DEM files on-the-fly, sir.

Try to set the main CRS of your drawing (command _ADESETCRDSYS) identically to which you read in the Dem header (I bet LL84) then _MAPCONNECT the SRTM stuff again.
