Drawers
Drawer layout is dependent on panel design. Panel top and bottom reveals, slide offset, minimum slide clearances and face indexing all affect layout.
Drawer faces are always a multiple of 32mm tall, less reveal. Drawer faces can be indexed with their top and bottom edges (before reveal is subtracted) centered on ("System"), or between ("Shifted"), system holes.
Indexing Wood Drawer Boxes
Balanced drawer boxes, like balanced panels, keep things simple. The following is a simplified version of the old How Wood Drawers Utilize System Holes article... Feb '10: added undermount slides... more

Full-Overlay Bottom Clearance
Traditionally, 32mm drawer and door faces are indexed so that their top and bottom edges center on "System" holes. With half-overlay and inset cabinets (where most box components center on system holes), drawer layouts are relatively easy because all drawer openings are the same size (when drawer rails are used).
With full-overlay cabinets, the bottom drawer faces are flush with the box bottom (0mm reveal). What this means is that the bottom edge of the bottom drawer opening is 9.5-19mm higher than the rest of the drawer openings, i.e. is 9.5-19mm closer to a system hole. Because drawer slides are mounted to system holes, the bottom drawer clearance for all slides is determined by the bottom drawer. The reduced clearances caused by full overlay faces can complicate drawer layout... more
