While Rudolph Schindler’s “space reference frame” is becoming better known, its relationship to the “row” has only been recently
investigated. The theory of the “row” counters traditional proportional notions, many of which are derived from the principle
of geometric similitude a principle which is mostly represented in architectural drawings by regulating lines and triangulation.
