I think that archicad is a program, very weak when it stands alone but very powerful when using with other software. One day archicad will be a complete archi program with powerful modeling, rendering etc, but for now it is just a archicad.....
I meet a lot of people who ask me how i created some models, drawing etc and they say ooooooo thats good program i must learn it, can u show me how u did that and then i say that all stuff what is interesting i didn't create in archicad, i created in zoom gdl, architerra, autocad, 3d studio, architiles etc................
When we take a look at archicad 6.5 and archicad 8.1 i can def. say archicad is much, much better but still it is not good as it should be.
Who knows, artlantis is preparing ver 5 which will be out in next 2-4 motnhs and it will have radiosity there. Maybe it will be answer to the archilumos maybe not but we must be happy if we can choose in which application to work with archicad and thats the power of archicad.
I can say only that archicad is revolution and it will be better and better
