In the KISSsoft Release 03/2012, several assistants for the model building in KISSsys were implemented (module SYS). They facilitate and simplify the modelling significantly. One of the assistants guides the user step by step through the entire process of building a cylindrical gearbox. Furthermore, the KISSsys assistants support in calculating gears and shafts. Further assistants are scheduled for the Release 03/2013. Finally, all KISSsys tables have been improved in terms of formatting usability such as font, background and text items, which leads to higher clarity and better user-friendliness.
