I used Google to translate:
"Hello good day, I purchased the AutoCAD Civil 2013, and earlier had the civil mind 2012, I had trouble seeing autocad 2013 files on another computer that has civil autocad 2012, algien could help me with this issue. Thanks"
Are you trying to make a file in 2013 and view it in 2012? With Civil 3D this will not work. You can "Save As" but you will only see the regular lines and text...you will not see the Civil 3D objects.
If you use the command ExportToAutoCad this will explode all objects so that they can be viewed in an older version. But they are no longer Civil 3D objects in this case.
