I will start by saying I am not a builder just a design engineer who wants to design his own home. I purchased Chief Architect Premier and have started to design the house. However since i am not a builder I am unsure if the default setting in Chief are accurate for how walls, floors, roofs, should be built. I know there are lots of options and ways to build these things I am mainly look for guidance as to what is normally the standards. How accurate are the defaults? any direction to find these answers would be very much appreciated.
