- aggiunta entità testo (con font Nfe e di sistema) - in tutte le rotate ora l'angolo è in gradi - aggiunta trasformazione Shear (scorrimento) - aggiunta trsformazione LocToLoc - Set/GetInfo specializzate per i diversi tipi di informazioni - Copy e Relocate con possibilità di indicare l'entità di riferimento rispetto a cui inserire - aggiunte trasformazioni a PolyLine.
