Someone recently added some text to the Revit Wikipedia article stating that "The concept of bi-directional associativity between components, views, and annotations remains a unique and distinguishing feature of Revit". They provided as a source the 2004 AUGI post What Does Full Bi-Directional Associativity Mean?
I'm thinking that's pretty old and probably bi-directional associativity is not unique to Revit. Can anyone enlighten me? How good are ArchiCAD, Tekla, Microstation, AllPlan and so on at bi-directional associativity?
