Hi,
 
This is my first question on a forum ever.  I'm using Autocad Architecture 2011 and completed a 3D first floor drawing.  I need help on how to setup and start with a second floor.
 
Thanks,

write in your command line 3dforbit and rotate the drawing then you could start to draw the second floor...

Please dont go to autocad details. It requires years of expertise to draw efficiently in Autocad. I suggest you to try Google Sketchup. Its very easy & fast to learn. For more help & query, there is a site which can help you.Plz visit http://www.sketchup4architect.com/magazine.htm

It is very easy in AutoCAD Architecture (changing software just for switching floors is nonsense) - simply use the Project Navigator:
