“Go-by” drawings are reference drawings that show examples of how to indicate information on framing plans, schedules, etc. While go-by framing plans may have originated from actual projects, they will usually be modified over time to include everything that can possibly occur on a framing plan. Go-by framing plans for various structural systems provide engineers and drafters a single point of reference to see how to properly draw anything they will encounter on the plans. The use of go-by drawings prevents younger engineers from using previous projects for learning how to show things on the drawings.
