The work presents real, industrial examples of generating, developing and applying UML templates in knowledge modelling for the needs of KBE applications. The applied templates are a synthetic reflection of standard programming constructions used by teams of programmers in specific industrial conditions. Templates are created taking into account both the very individualized specifics of software development, as well as the individualized process of evolution of a specific project area. In this case the construction of the KBE application is implemented as modelling based on carefully elaborated and largely individually tuned templates. The final application of this class is integrated with commercial CAD / CAE systems and other software. The use of the templates allows for a relatively effective, specialized creation of KBE applications. In addition to the skills needed to work with templates, people using this tool must possess clearly articulated, competent and complete substantive knowledge. The article consists of three sections: the first introduces themes to the templates and presents the process of initialization of this tool class in industrial conditions; the second section shows the use of modelling in the process with the gradual evolution of the modelled knowledge; the third section concerns the application of a strategy based on the rational development of a representative set of templates. The examples presented are based on real industrial implementations conducted over a period of about 10 years.
