QCAD
QCAD is a program for 2D technical drawings that feels close to classic AutoCAD. The free Community Edition is open source; extra tools such as extra file formats come in a paid Professional edition.
How hard it is to start using it. Easy: install it like a normal app, or use it in your browser. Advanced: you run it on your own server, use the command line, or it is a tool for developers.
