Draw Things for Free with Autodesk SketchBook
I recently bought a drawing tablet (googling “Wacom Intuos Wireless Graphic Drawing Tablet (Medium)” should find it for you), because I had no way I liked to write out visual notes, especially timelines and complex process flows. It was one of the best purchases I’ve made in a long time—I wish I’d thought of it five years ago.
The immediate question after that was: What software to use it with? That’s where Autodesk Sketchbook comes in. It’s outstanding free software, and where I can imagine Photoshop or other paid alternatives being more feature-rich in some ways, Sketchbook has been everything I needed and beautifully optimized for a pen/tablet/one-handed keyboard UI.
It works with mouse too, obviously, so you can try it out without buying a tablet and see what you think. Prepare for a bit of a learning curve initially, and note the very helpful
m keyboard shortcuts.
