Anyone else here not work from plans and drawings?

Formal drawings? Not often, but sketches, outlines, dimensioned drawings of details, notes made on scrap paper ... I draw things up all the time. I do it so I can figure out materials, spacings, bom, shapes, etc. - so I can use what I have in inventory (the "stuff" piles) and what I have to get (fasteners, tooling, consumables, etc.).

Keeping everything in my head is for the concept phase, but even then I will sketch it out so I don't forget. This is especially needed if you work on a whole bunch of things at the same time.
