Building Codes

[sutcac]

Without any knowledge of building codes (or structural engineering, I assume?), I would strongly suggest consulting a professional from the beginning. Computer software is just a tool, like a pencil, it isn't a shortcut to a good design.

Chief is geared very strongly toward wood-frame construction. It is possible to design in the elements you mention, but you'll need to learn the program quite well to be able to do this effectively.
