Short description of the programs and why:
The softwares which i used rebuild the model
 Autocad 2006

Autocad is easier to draw the 2D plans, sections and the elevations though the scaning pictures.
Skechup 7 is used to build the regular, basic and simple floors.It is easier to get the walls from the 2D lines used the pluging-in buttons.
