Honestly, switching from a 0.5mm to a 0.3mm lead for my isometric sketches was a total game changer.
I was working on a detailed assembly drawing for a custom bracket last month and my lines just looked messy and crowded. My boss, who's been drafting for like 30 years, told me to try a finer lead. I swapped it out and after about two days of getting used to the lighter pressure, the difference was crazy. My hidden lines are way clearer now and the overall drawing looks so much more professional. It's a tiny change but it made a huge impact on readability. Anyone else have a simple tool swap that improved their work this much?
