Brad, Thank you for the info. i will get that book you talked about, I think that I just need to do it. I am making it harder then it is. Just unsure on sizing post 8x8 or bigger rafters 6x8 or 6x10. top plates 8x10 or 8x12. Stuff like that. i am going to build a scale model. see if that helps.
thank you
