I've been using Fusion360 for the past 4 or so years. It's similar to AutoCAD but much cheaper. I sometimes use Inkscape to clean up or edit files. Sheetcam creates the G-code and away I go. Most of my drawings are 2D components but I wanted to get familiar with a good 3D CAD so the transition would be easy if the need ever arose.
Just what I need, another toy.
