I’ve never used a CAD program, or Adobe Illustrator, always got by with Photoshop and then Gimp, but now at last I’m going to learn Inkscape for some drawings of plans for my house. Maybe then when I can handle two dimensions I’ll have another look at Blender !
Its easily downloaded from https://inkscape.org/
Help is included and works from the menus first time.
Help> Tutorials gives eight Inkscape documents which are tutorials, and which you can edit yourself (but don’t save), drag the shapes around and get a feel for how it works. Basic, Shapes, Advanced, Tracing, Calligraphy, Interpolate, Elements of Design, Tips and Tricks. I did some a few nights ago, done another two tonight. The Calligraphy one is interesting, I skimmed it, but I don’t think I’ll ever use it.
Interpolate Tutorial shows what happens if you interpolate between a blue line and a red line…
