I just forgot to mention, there is a website
http://www.aboutarchiterra.com/index.htm
about architerra. It also has a tutorial and some other info. Don't know about the latest manual for download, I don't think there is any besides the 2.0. Maybe Fabrizio can tell you more about it. Find him here in the forum or email him : (
fabrizio.diodati@cigraph.com).
Hope it helps
PS: you should have post it under the "Other Products" forum, you would get more info on it.
