Circuit and PCP design - Easy electronic CAD - KiCad

I'm still looking for my ideal schematic app: easy to use, clear and contains most of the common symbols.
Nearly the answer is Xcircuit viewtopic.php?t=43 but while it's easy to learn, Xcircuit's symbol set has some tedious omissions, like an antenna.

I just blundered upon KiCad -available truly free for Linux, Win and Mac. It does more, including schematics, component lists, PCB layout and project documentation. Yes, it includes an antenna. Download is from the KiCad DL page at https://www.kicad.org/download/, or from your Linux included software. Arch Linux has suitable packages at AUR.

Easy to use? Well, yes, but you do need to RTFM, available here:

https://docs.kicad.org/6.0/en/getting_s ... kicad.html

The whole package is extensible with extra symbols and all customizable, if a twin-cavity reflex klystron doesn't immediately come to hand... :shock:


This is what the control page looks like:

and here is a PCB design, with complexity clearly presented:

An example annotated schematic looks like this:

There's even a ray-tracing 3D viewer included to show what the project will actually look like:

KiCad is an ultimately customizable app, easy enough to start, but there's a lot included so it's just as well there is a very good and well-illustrated manual.
