>> While we're sharing our favourite open source EDA tools, HorizonEDA deserves a lot more love and attention
My impression is that Horizon-EDA is well worth following, but not as far along as KiCAD. It's a nice second option that some people prefer.
Unless you really need some really advanced KiCAD features then Horizon is farfar more usable. Night and day.
I'm just happy to say you can now use SolveSpace to create STEP models of components for either one: https://solvespace.com/index.pl
The Pool concept of horizon is very interesting. Libraries & Library Management are absolutely the worst part of EDA/E-CAD. I wonder where the Return on Invested time happens for this concept.
