WebDatums reading order can be considered in a manner similar to assembly constraints in a CAD program (e.g. Mates). The difference is, that in a CAD program, the constraint works on a pair of perfect elements (one plane in relation to another…) and a datum reference system links a physical, imperfect element (surface, for example) to a high ...
