Nov 20, 2018 at 19:55 comment added Dan @MartinBonner Though they still very much pre-date modern CAD. Certainly blueprints as we known them have been around since the Victorian era. I agree though, I doubt there was much to that degree prior in day to day engineering
Nov 20, 2018 at 8:20 comment added Martin Bonner supports Monica @davidbak Yes, sketches and models are very old indeed. What I believe are comparatively modern are detailed, accurately dimensioned, drawings.
Nov 19, 2018 at 21:28 comment added davidbak @MartinBonner - medieval cathedrals (and other such buildings) also had physical models of some or all of the construction, so the builders/workmen could see what they needed to do; did they not (in some cases at least)?

Nov 19, 2018 at 12:08 comment added alephzero In real life, most modern small-scale buildings (like the OP's house extension) are still "built rather more by eye than by detailed plans". When you discover that the existing structure isn't the same as what the plan assumed, you don't stop to update the plan - you use common sense and improvise!
Nov 19, 2018 at 12:07 comment added batsplatsterson @MartinBonner - The oldest "construction drawing" is in the Temple of Apollo at Didyma. An unfinished stone wall was etched with the profiles of columns and moldings, and the wall was never finished so the drawing was not erased: a rare glimpse into the history of working construction drawings." en.wikipedia.org/wiki/History_of_construction

Nov 19, 2018 at 11:50 comment added Martin Bonner supports Monica "People have been building houses by hand-drawn plans for centuries". Depending on what you mean by "plans", I'm not sure that's true - or if it is true, it is a rather small number of centuries. The medieval cathedrals were built rather more by eye than by detailed plans that would be acceptable to a modern builder.
