Dear, I am sure that this was asked before but i cant find the answer of how to do. I am trying to start to use kicad as main PCB program, but allways i get stuck and i cant progress.
Normally when i do a PCB design i start from available space to work, this say: i draw the PCB perimeter, fixation holes etc etc. Why? because i use an existent plastic box, and i do the design to improve manufacturing time.
Question 1) How i can draw the PCB outline ? for example a triangle of 6 cm of each side. Without use the ground plane?
Question 2) How i can put an central hole of 3.25mm (is not a component and have no footprint?
Question 3) How i can put a arbitrary pad in the pcb?
Best Regards, and thanks in advance.
