I'm currently new to using autodesk autoCAD architecture 2010 for drawing plans of buildings etc, ive only really used it before to have models cut out on a laser cutter.

Ive successfully drawn out the ground floor plan of my building, and have managed to create a first floor on top thats identical, however in my design the first floor isn't identical! how do i create a house that has different floor plans at each level?

Thanks for your time
