TIL my sibling and I clash over how to begin drafting projects

Growing up, my dad was a drafter and always began with pencil and paper. He says it helps you think before going digital. But my sister, in engineering, prefers to work directly in CAD for speed and accuracy. When we planned our garage expansion, we argued a lot. I spent days sketching layouts, while she drafted a 3D model quickly. Her model caught a load bearing wall issue I missed, but my sketches had better space flow. Now I'm confused between old and new ways. What's your view, drafters? Do you start with sketches or move right to software?
