Nowadays, it has become possible to apply BIM technologies in several industrial sectors. BIM technologies are gradually evolving into a process in which, in addition to traditional building design, there is an opportunity to adapt to information technology solutions, data analysis, automation and virtual space or even artificial intelligence solutions.

Object-oriented modelling is the most important key element in terms of BIM.

The aim of this chapter is to provide knowledge not only about object modelling, but its fundamental differences from CAD systems. Students will get acquainted with the advantages of object modelling, parametric modelling, the role of information in BIM, the relationship between information, individual objects and geometry.
