Though I am a big fan of the FDO data connection that came around in Map 2007 (which of course, Civil 3D 2007 was built on), I do sometimes like to import map data the old fashioned way through the Map>Tools>Import.
In 2007 and below, I always had to manually assign the input coordinate systems.Â Map didn’t seem to want to automatically find the .PRJ (projection) files for me like the FDO did.Â This was a bit tedious, especially when importing a collection of .SHP files that each had a different coordinate system.

In 2008, as long as your data came with a .PRJ file…
The Map>Tools>Import command should find them, and assign them right out of the gate for you.

It’s a small thing that makes life much easier when importing map data.Â I used to keep a .txt file with a list of the .shp files I have on my machine and their associate coordinate systems.Â
