This is a original to a printed
circuit board, its actually 4 to be divided after etching. Its the top side of a dubbel sided board (each side is drawn i different color)
The tool for drawing has lot of assisting features. checking rules etc.
And You must consider Your tools for etching and mounting tools. In my case line width can't be to thin, which sets limits on possible drawing ways. And any component layout not in standard library must bee constructed as a footprint and function regarding all pin connections. But the result becomes very good.
