In Standard dances, it's very important to have proper alignment of the feet and body. The alignments page has been updated to address some potential confusion when reading descriptions of international figures.
Two alignments that could cause some confusion are diagonal center against line of dance (DC against LOD), and diagonal wall against line of dance (DW against LOD). DC against LOD is the direction opposite diagonal wall, and DW against LOD is the direction opposite diagonal center. Or, another way to describe it, if LOD is north, then DC against LOD is southwest, and DW against LOD is southeast.
