6.6. Courtyard line has a width 0.05mm. This line is placed so that its clearance is measured from its center to the edges of pads and body, and its position is rounded on a grid of 0.05mm.
6.7. Courtyard clearance is 0.25mm except for components smaller than 0603 at 0.15mm, connectors, SMD canned capacitors and crystals at 0.5mm and BGA at 1.0mm. (IPC-7251, IPC-7351B)
6.8. Cannot be duplicated to match a different pin ordering. This is to be handled in the symbol libraries.
6.9. Footprint name must match its filename. (.kicad_mod files)
6.10. The value and reference designator must be placed on silkscreen.
6.16. 3D Shape ".wrl" files are named the same as their footprint and are placed in a folder named the same as the footprint library replacing the ".pretty" with ".3dshapes".
