Plan has shed roof with parallel cord truss of 30" in depth running from High Shed Roof to oposite side with 29' span at a 3/12 pitch. A couple of questions. 1. How do you define the truss height post engineering? 2. How do you deterime what the height of the top plate is on the high shed wall? (not the pitch) 3.How do you avoid what is depicted in the screenshot? (truss sticking above roof plane) I have walked through the setup instructions several times and I am missing something. Thanks in advance for any advice, I am learning but I have a ways to go to call myself proficient.
