Hi all,

I am a new member of this group and currently studying on analysis of CAD software used in interior architecture. In this context, I have to classify CAD software used in terms of modeling.

Although I have read some chapters and articles about modeling, I can not still clarify the differences between Geometric, Parametric and Building Information modeling paradigms.

Could you please first give me simple definitions of those? I also wonder what modeling method(geometric or parametric) AutoCAD uses.

thanks in advance,

cheers
