: You must define specific layers for each board feature. Typical layers include: Padmaster (PADM) : For through-hole pads and vias. Solder Side Traces (SOLD) : Circuitry on the bottom layer. Component Side Traces (COMP) : Circuitry on the top layer. Silkscreen (SILK) : Component outlines and text labels. Solder Mask : Areas where the protective coating is removed.
For hobbyists making boards using toner transfer or CNC milling, AutoCAD can draw copper traces manually. However, even free tools like KiCad or EasyEDA are vastly superior.
