We are Achiterra users - have been for a long time - and our latest version does not work for us with AC11 and we thought hat it was something we did wrong. A colleague, whom we persuaded to buy Architerra for his AC11, also had problems and Graphisoft Aus have now informed him that it doesn't work. Maybe it works for people using the international version of AC11 (we have an aussiefied one)?
No we have not contacted Fabrizio directly, but Graphisoft Aus have told my colleague that they have done so. I've posted the issue on this site, thinking that it might elicit a faster response. If we are mistaken, other users will surely put me right. In the meantime, we've gone back to using ArchiCad 10, with Architerra for this version and it works fine.
Maybe, like other product defects, suppliers are astonished to learn of a problem because we are the first, and presumably only, user in the whole world to encounter it!
