How do you build? Buy plans, computer aided sketch or figure as you go?
I prefer to figure an overall size and make pencil sketches that are just a few inches in size showing some joinery detail. Then make a list of parts but only cut a few at a time. I end up with a few pages of dimensions, math equations, cut diagrams and little drawings by the time I’m finished building.
Sometimes I record the final dimensions of each part with notes when I’m done.
