"Download the latest "Java" version"
It was translated to Java, this says it all.
The tool is not under much development. And the old "ugly" C-Version
is still there. Maybe, one could take some of the C code and build it
into KICAD.
It would be an advantage to design in 3D view like a brick that gets
A PCB design is just layers with the approach how to route my cable. But
a chip design is a 3D structure consisting of different layers which should
visible as a rotated brick.
Maybe one can use CAD FreeCAD but with smaller grid, of course:-)
