David Kurmann (ETH Zurich) said: "however, we were using lod in a context of architecture in our courses teaching caad where ' types and instances' were developed. this implementation does use lod as levels of refinement when working in a top down approach. while top down is widely used in architectural design - lod is not a mayor topic. it is more levels of abstractions to be able to create drawings for certain purposes: 1:500 for landscape and environemnt,1:100 for general layouting, 1:50 for details. of course every plan then uses an abstraction." If more info is needed, I can get it. -Ernst .................. Ernst Kruijff ................. Westersingel 9 .............. 4101 ZG Culemborg ................ The Netherlands ................
