I built https://measuretocut.com after too many DIY projects ended with another trip to the hardware store. It figures out how much material you actually need and how to cut it to minimize waste or costs. When I released it in December it just handled 1D cuts for things like boards, bars, and pipes. You enter what you need, and it lays everything out visually on stock lengths. This morning I released the 2D sheet cut calculator to do cut plans for plywood and similar sheet materials. Any feedback is welcomed from fellow engineers turned woodworkers!
