The first part of the course is devoted to mastering routine work with the software Mechanical Desctop 2D. The following part is devoted to surface modelling, creating wire models, to the types of objects or methods that serve to represent, or model and edit, plane and curved surfaces. On the surface models, we show various ways of mappings, axonometry, perspective, rendering. The course further deals with volume modelling, the possibilities to edit a moel, acquiring information about its physical properties and the ways of deriving 2D documentation for the construction from the model. The last part is devoted to the basics of the creation of parametric volume models and sets through the technique of construction elements modellling.
