I also placed some tags using the tag tool - like GND and VCC, to make the schematic neat and clear.


Finally, I generated a Netlist by pressing the green netlist symbol on the toolbar.


However I got an error saying that component R1 did not have footprints defined.


So I went back and assigned footprints to the missing part, by going to its properties again, and selecting the correct footprint from the newly installed libraries. And generated the netlist again.




#### Drawing traces
Then I opened the KiCad pcbnew part, and found the netlist created and stacked of all components in the middle of the board.


I first editied the design rules in its menu and set the grid size.


The components all have an indicative line connection, so I used that to rearrange them and then added the traces, using the trace tool.


After connecting them all, I used the line tool to draw the outline like so.


Next I exported this as svg with these settings:


I opened the svg in Adobe Illustrator, made new layers for the traces and outline respectively.


Then, after checking that the model is in mm, exported both layers separately at 150dpi in png.
