Why don't you try with my "Orologi Solari" program ? It can manage several types of dials including vertical declining ones, and it can design a day line for a specific day. It includes a large help file. User interface and help file are in English as well as in Italian and Czech. It can be freely downloade from my web pages : http://digilander.libero. it/orologi.solari Try and let me know ! Gian Casalegno
