After 10 years of CAD, I finally tried drawing a roof plan by hand first

I always thought hand sketches were a waste of time for new builds, but last month our office printer went down for 3 days and I had no choice. I roughed out a 40x60 foot roof layout on graph paper before starting AutoCAD, and it saved me 2 hours of revisions because I caught 3 bad intersections early. Has anyone else noticed hand planning cuts down on mistakes, or am I just getting old?

torres.leo hit it with "letting your hands figure out the logic before the software does it for you." That's exactly it for me too. When I sketch by hand, I catch those weird angles and bad intersections before they turn into a mess on screen. It forces you to slow down and actually see the whole roof, not just one corner at a time. And that bit about erasing and redrawing is spot on - it sticks in your brain way better than hitting delete.

Hate to admit it but going analog actually forced me to think through the geometry before getting lost in layers and lineweights. That physical act of erasing and redrawing a bad hip ridge made the 3D intersections stick in my brain way better than just deleting a line on screen. Sounds like you stumbled into the same workflow hack I found the hard way, it's less about being old and more about letting your hands figure out the logic before the software does it for you.
