AutoCAD Civil 3D

[#1]

I mad e the mistake of creating my corridors for a large site in the same drawing, and now I would like to pull them apart into individual drawing files for each corridor.  Any suggestions?  I thought that last time I tried it, the drawings or data somehow got corrupted.  I am running C3D 2009.

Thanks

So you have one corridor and you want to break it up into two different corridors in two different drawings?

Open original corridor drawing.

Delete the baselines out of the corridor, SAVEAS corridor1.dwg.

Open original corridor drawing and delete other baselines out, SAVEAS corridor2.dwg.
