I 'need' to make a template hexagon that is four inches from side to side. So I spend over an hour with straightedge and compass. Bodge it up so that I just plan to start over.
Pat asks me what I am trying to make. The retired Math teacher gets on the computer , does a search and downloads and prints up a template.
Suitably humbled, but now armed with the template I can prepare the map for the next micro armor scenario. Lucky man, I.
