Structural modelling and desing software

Does anyone have any suggestion on user friendly structural design software specifically made for the residential market. I would for a software that I can create a 3d model(roof, floor, load bearing wall) apply the design loads and the software provide prelimary members sizes of wood or light gage metal, truss profile, etc. along with detailed calculations to review.

Any suggestions?
