i’ve installed today the software and i’ve tried to create a schematic.
What is the right way for place connections from components and signal lines?
(E.g on Circad it’s called signal dot)
I’m not sure if I understand your question correctly. Creating connections in schematics should be pretty clear, just use the “Draw Wire” tool: https://librepcb.org/docs/quickstart/create-project/schematics/#draw-wires
