DIYLC v3 is still in beta stadium, it misses few schematic symbols and such
And this is what I did, I was creative, and I've draw few mostly used by me
It's not ready to use image choosed from menu, I'm not as much creative
I just used lines, copper tracks, wires, pads and such already existing in DIYLC to create my own
Some - the tinny ones, can be difficult to drag, the solution for it is to place any component next to it (jumper, resistor, whatever) and by selecting all use additional component as a lever
As I said, it cant be choosed from menu, what I'm doing is - when I do schemo, I open it up from DIYLC library folder, and I'm keeping it below project I'm working on, or I have it open in another window with DIYLC and copy/paste what I need. It's good idea to change the grind to 0,025"
